Thanks for sharing..... Love stuff like this!

Have one flowed on a bench, we might all be amazed!

All the Mullen airflow work done at 3" H20"... and now lots of head specialists even question the validity of testing at 28" since it's often way lower than what the engine really generates for pressure. Makes my lowly SF-110 10" H20 standard look hi-tech compared to the old Mullen-era tests.

I would be interested in them if you are looking to sell. Pm me here if you like, thanks.

Yes, stock (360) heads. IIRC, they were the 308 castings, which have W2-ish like exhaust ports. I could be wrong. The heads came bowl ported and the next level up, fully ported. That was there description with a % number for flow increases. But there was still room to go on the heads. They also listed the heads for there intended lift use. AKA; Up to .500 and then over .500.
MP also offered a ported 318 head, the 302 IIRC which they claimed it out powered the 360 head by 55HP on the smaller 318.

MP offered loaded W2 heads, but not ported, at least that I remember.

Those MP ported head prices were insane, like $1000 each for the ported 302 head.

R.

Interesting bits of information guys. I appreciate all the input. Sounds like the hard part is going to be putting a value on these things assuming I decide to find another owner.

MP prices on anything is normally insane. The only real plus was the heads were brand new never used casting made for the performance end user. So add the price of brand new never used material up and then the hand porting work as well as paying the outside porter.

Doing a used head is cheaper, true, even though it could end up getting more work done to correct the deck and/or other parts of the head.

Any idea what they cost new in a Direct-><-Connection catalog? Anyone have an old DC catalog and price list?

The first 2 heads are the 360 heads. It is stated that they are ported to a 44% increase over stock heads which flow 200 cfm at least if not a tiny bit better. So, at least an addional 88 cfm makes them a pretty good flowing head. 288cfm should be able to get you moving well. Produced before Edelbrock came about?
Each price is per head. (1 head complete.)

All prices are the Racers Net list in the year 2000.

For the P4876179, 2.02-1.60 ported for .500 lift, $1206.60.
For the P4876180. 2.02-1.60, ported for .650 lift, $995.00.
-----------P5249459, 360HP- 1.88-1.60 (1 Stock head complete) $495
-----------P5007089, W2 head assembly, unported, $862
-----------P5007047 STAGE V, 500/505 service head, $867
-----------P5249112 STABE V ported/2.14-1.81 (15% flow increase) $1295
-----------P4876186 Stage VI non CNC ported heads with 2.14-1.81 $1375.
-----------P5876187, Stage VI non CNC ported head, 2.18-1.81, $1935
-----------P4876857, HEMI, $1495. Not ported, just an assembled head.

You guys don't want the ported 2.2/2.5L OHC 4 banger report do ya?

I have a pair of the p4876180 ported to .650 heads....no milled stands, sanding roll clean up, and the retainer hit the guide at .550 lift, and I did pay the 2000$ for them 15-20 years ago . I think Arrow was doing them. These Mullens are a completely different piece.

I was asking whether "Direct Connection" (not MP) back in the '70s was offering a ported iron head, I don't have any older DC catalogs around.

If Mopar did offer something like that, I imagine they likely would have been done by Mullen. The W2 came out around the same time so it kind of does not really make sense. Maybe they were exploring stuff with factory heads? Dunno.

I have a set of the #269 heads. These were the MP OTC '308' heads without the smog holes. Same a s a regular 308 otherwise with 1.88 valves.

As mentioned, there were a few levels of ported iron heads they offered. I believe that was in the '80s though, not the '70s.

Off hand, I'd say that $1500. in today's money is a fair price for buyer and seller. With inflation, that 900.+ per head would be about 2k EACH in today's dollars!!
Heck, I don't need them (today) but I'd give 1500 to have them on the shelve... The coolness factor adds value. Besides nos is nos...
In this condition, almost unobtanium.

LOL... try to get that... with mopar people.. never
gonna happen.. plus they would be better off with alum
EDIT
more like $800-$900 max... sorry to say that.. but I have
tried to sell stuff to mopar people in the US and no one
wants to buy unless you want to give it away

I'm not so sure it's so much about "Mopar People" being "cheap" but more so that there are a fair number of good heads to choose from these days in the 1K plus price range that might hold these back.

I would own them for nostalgic reasons and pay what I'd call "decent" money for them, but nostalgia only goes so far for cast iron heads and for something that would be pretty darn hard to spot once installed. 02

W2 ported offerings from MP/DC? No, just loaded. They did offer ported 360 heads in 2 levels and a ported 318 head. W2’s came bare or loaded.

And yes a flow bench would/could be very interesting

I had a set of those heads on my 340 in my Challenger for years. They had the relocated pushrod holes to eliminate the pinch in the intake port and used W2 rocker arms and Stands. I sold them in 2000-2001, when I hurt that motor. Got $700 for them with valves & springs, if I remember correctly.

it looks like those heads are cast with the pushrod moved over, so basically a T/A head with nice finish work???

I was googling Bob Mullen's name and ran across this old thread. Since these things get searched now and then by old guys looking for bits of racing history, I thought I'd add a bit of my recollection of Bob Mullen and Mullen & Co..

I was 19 years old when I went to work for Bob Mullen in 1975 in Carson CA. Jim Razor was his shop leadman. A few doors down in the complex was a man of racing legend from the GT40 LeMans and Shelby Daytona coupe era, Steele Therkelsen. But that's another story.

I was hired as the machinist. Bob bought a brand new Bridgeport mill shortly after I arrived. I tooled up for milling heads and installing big seats in D6 Hemi heads that got some huge valves (2 3/8"?). I had to sink the seats deeply into the chambers so there was enough valve to valve (intake to exhaust) clearance. In the year or so I was there, I machined a lot of D6 heads for the big valves and a lot of port throats on 340/360 and W2 heads. Mullen did have a contract with Direct Connection for providing ported D6 Hemi and the small block iron heads (which I can't recall specifics about).

Mullen began manufacturing his own D6 big intake valve about then also. I made the first of those and seemingly hundreds of them later.

I recall a handful (maybe half a dozen?) of Offy (Offenhauser 4 cylinder) head/cylinder castings coming thru the shop for porting. They were special castings made by the Bignotti Champ Car team after Mullen had redesigned the ports.

One memory is of a set or 2 of 351 Cleveland heads that Bob Glidden had contracted Mullen to port for his pro-stock. I machined the exhaust ports back and installed aluminum plates to raise the exhaust ports, as was contemporary at the time.

Laying around the shop was a set of castings that Mullen had designed and had cast, but not had any machine work done on. These were 4 valve Big Block Chevy heads that were designed to be bolt on to a standard block and use a forked rocker arms to actuate two valves at a time. I talked to him about machining them, but I left the company before we did anything with them. Also laying around the shop was a 427 Ford SOHC engine, if my memory is correct. Pretty rare and valuable piece these days.

The mention of whether 3" of water flowbench testing vs. much higher deltaP flowbenches was going on back then. I had late evening discussions with Bob about that. Bob was an brilliant man. He was convinced there was not enough difference to warrant going to higher deltaP test benches. I think the business successes and racing community recognition he achieved using his hand built flowbench bear that out. I used that flowbench a number of times on both my personal projects and on customer projects. It was extremely well built and reliable, repeatable. I haven't seen any commercially manufactured flowbench that stood up to it. Last time I saw that bench was probably in the 80s or 90s after Bob had sold the business to someone.

I didn't stay in touch with Bob or Jim Razor and don't know if either is still upright. If anyone knows, please post.

Charlie,

Ever wet sleeve or furnace braze sleeves in any 340 blocks when at Mullen's?
