Where to buy w2 heads

I have never built a small block other than a few mild daily drivers and i was wanting to know is there any place i can buy w2 heads or would i only be able to get used? I wouldnt be totally against used but juat worried about cracks. I have a 340 with dome pistons and .575 solid cam. Is there a better bang for the buck than w2s?

I sold my last W2s last year.
Collected them for no reason other than they were there LOL.

P5249769, order from jegs, summit, chrysler dealer.

Chrysler dealer should be able to see if there are any in depot stock, if you can get one to take a second and look on Dealer Connect it should show up.

As long as it's understood what you're getting into, and all that has to change to use them, and you're sure you want iron heads, etc.

There's a few head/engine guys on this forum that may have some for sale.

Summit and Jeg's both still have them listed on their site.

There's a used set on eBay right now:

Otherwise I'd check out the For Sale - Small Block engine section on Moparts, Racingjunk.com, and Craigslist.

Whether you buy new or used, I'd have them checked out by someone who knows what they are doing.

You would be a lot better off with using a newer better designed aluminum heads like the Eddy Victors, Indy 360,360-1 and possibly some others that I can't think of now
The W2 where developed a long time ago in the early to mid 1970s
The P5 and P7 heads are way better than the W2
Better airflow means more power

I have some new in the box W2 heads sitting in my shop. If you're interested I can contact the guy who left them here to see what sort of price he needs for them.

WOW!!! Roy Burnett. Haven't seen that name in years.

I think it was late 1972 or early 1973 and my dad and I were there for something, and in the showroom they had three 1971 Hemi Cuda's sitting there and they were all purple. I think the price on them was $3100.00 out the door, but they told us they could get under 3k for one and do better if we bought two of them.

We had my mom drive down to look at them and damn near had her sold on two of them. Finally, she gave the OK for one and took off. We must have been there all day and in the end, my dad passed, as they were all torqueflites.


All I can say is DAMN. My dad still doesn't talk about that to this day.

Yeah I think the guy bought these heads in the late 70's and they have been sitting in the box since then. He has a nice '72 RoadRunner that they were going to go on but he just never got around to it. His RR has been sitting outside in the rain for the last 20 years and I don't think there is much of it left either.......

P5249769.... well they “re-did” the dealer connect parts page so it makes it hard to decipher, but I believe there are 24 of them at the Warren MI depot. I’ll try and confirm tomorrow

$700 list/ $525 dealer net

I bought mine from moparts race parts for sale. They may be an old design, but I would say they work pretty well. I built my 340 mainly out of parts I saw forsale, the only new parts being flat top pistons, rods and lifters. The heads were untouched, so I home ported them trying not to make the port any bigger because of the small engine size. The cam is a solid roller with over 260 degrees on the intake side at .050", and the headers are with 1 7/8 primaries, intake Victor W2 with 2" open spacer (just for street credibility) and a 750 holley. It made 587 hp at 7000 at dyno, and has so far run 10.2 in my light '64 Valiant, but still learning how to use the DN 4+1 manual. In this video the engine was sputtering though in all runs since the distributor cap was loose... https://www.youtube.com/watch?v=4Ufoy89RoEQ

LOL the W-2 is light years ahead every single conventional small block Chevy 23 degree head. Period. I watched another engine builder in 1985 spend months trying to adapt W-2 heads to his SBC.

Your combo shows what a decent prepped set of W-2 heads will do.

Just watched your video. Sticks are the best. I think you could benefit from taking some clutch out of it. I can hear it pull the engine way down on the hit and it's beating the tire up pretty good.

You can take some of the hit out with chassis and shock adjustment as well, but the clutch hitting the tire like that is usually too aggressive of a clutch tune.

What flywheel are you using and what's the gear ratios?

I was hoping you'd chime in!
Readily available brand new, that is cool to see.

Wait...are you saying the W-2 is still available new?

Well, yeah.

If any Chrysler dealer parts counter can confirm there are 24 of them down the road in the Warren PDC, then yes they should be readily available brand new.

Alot of folks don't realize mp was attempting to stay committed to supporting the grassroots racer who had to run a cast iron head. Saying something nice online about MP is like saying something nice about Indy, it's just not fashionable, it doesn't matter if it's true.

During my time as an mp contractor I had collected a pair of one depot stocked 769, and one pre-production oddball/engineering sample from circa 2012. They were nice, although the machining on the engineering sample was not 100% complete.

I posted about them a long time ago.
Here is the post with some really bad pictures:
https://board.moparts.org/ubbthreads/ubbthreads.php/topics/1196115/1.html

I am pretty sure nobody at MP has touched this product since at least 2012, which could be either a good thing or a bad thing depending on how you look at it.

Here is the THING
W-2 heads are easy to find and afford--It is ALL of the other items that you need like the valves--The ROCKER Gear! The Headers, The intakes etc that are going to wipe you out and then when you run it ya go --Ummm..Should have went with something else for sure--They were designed to go faster than the racers were going at that time using a tunnel ram, 4 speed, and a Pot Load of RPM--so in that time doing that job they were better but now?????? No way!
Trick Flow SB's coming soon no reason to think they will not change the landscape like the Big Block units have done--You price quality W-2 rockers get it all bolted in then observe the stupid push rod angle on the intakes and you will see for yourself

They may be outdated and rockers may cost a fortune, but at least they're heavy

The biggest customers are folks who have to use iron heads.

I don't really care what TF does, you will never make power with that architecture and not use an offset rocker.

Pushrod angle is a bit of an issue, but it can be overcome.

Any engine over 375 inches needs a minimum of a W-2 head.

This post proves what I've been saying for decades. Chrysler guys won't spend the money on real race parts. They complain about everything from rockers to headers.

This is why Dart, and anyone else around wont make [censored] for the Chrysler crowd. They can make more money building another head with early 1960's architecture, increase the port volume and add a big intake valve to make it look good on a flow bench and then market the hell out of that you can use a stock, stamped rocker on it.


It will never change.

Agreed.....
Some guys have ran good with standard stuff but they are few between. I ran w2s with arrow porting for a very short time, went 9.83@134. 3100lb, 727, way back in 06 without trying, the most run of the mill 408, only having a handful of runs on combo..., a good head imop. A lot of people will say otherwise, I don't see it at the track tho, just my opinion.

Probably the last of the last. I have a cool parts manager. He’ll find stuff, get on the horn and verify it’s existence... he was out of the office today, but will be in tomorrow.

and do not rely on JEGS or SUMMIT showing stuff available.... they’ve been proven wrong time after time on Mopar stuff.

I hate sweeping generalizations.
O.K. , you're half right.
I still complain. Mostly about prices.
And having to pull the master cylinder to set valve lash. LOL

LOL trust me...I [censored] about the cost. But I spend it and get on with it. It's ok to complain about the prices. But it is what it is. If that's what it takes, you do it.


I can say I never had to grind on my non MoPar customers to get them to spend on a block, or buy the latest rings, or buy quality shaft rockers. You hear them squeal but they spend the money.

The car is one of the first Finnish purpose built drag cars, and I have restaured it externally and technically it pretty close to what it was in 1980-1981. The drivetrain parts have been collected from here and there, it's got leaf springs with long ladder bars and some Dodge ram van Konis in the rear,Just the way it was built. The flywheel is an aluminum one, and the clutch is called "axle killer", a twin 10" disc mcleod..., no adjustment there either. Maybe in the future I will upgrade it to this century as far as the clutch goes.

Impressive. I love the car. But like I said...watching the video you are hitting the tire pretty hard.

If you are going for an era correct car, you nailed it and I wouldn't change a thing in that case. I'd just drive it and have fun.

And there are 24 of these sitting in the Warren MI depot.... get em while you can!

I have had a pair for over 25 years on several different combos, got them back in the 80s as I bought a complete 340 with them for $2400. Still have them on my 363 with well over 1,000 runs , it has the old ductile iron non roller rockers. never broke one and only replaced an adjuster or two. i bought a pair on here for my present 408 but my engine builder talked me into a complete Indy 360-1 top end so i sold them again on here. Still have the 363 as a backup motor ran great, good oil pressure etc. when i took it out ( it was 11.5 to 1 and I wanted to get away from race gas ) My 408 is pump gas.
