Indy has a new 600-13x head on the shelf now. The head was developed by Goodwin competition and Best machine. the new head fits a 4.840 block, flows 520 cfm @ 1.00". Indy makes the head and Goodwin does the porting. We run the prototype in in a 88 mustang, they are not as good as the new head will be , as we are still revising the exhaust port. That will be done by the end of July. When they are complete we will build a 632" motor to run in mx235. With the 565 motor we are presently racing we go 5.00 at 2950 on 26 in tires. It makes 1222 on a very tight dyno. If anyone is interested they should talk to Chuck at Best Machine 1 248 987 6038.

Will there be a 4.80 600-13x head option?

No

Kenny that Valiant looks awesome. I have always been a fan of that early year Valiant body style.

I haven't read through this thread,maybe Vern has posted with his best Brewer results. He made somewhere over 1140 hp with a 604 cube motor.

With 1 carb @ 565 inches we made 1194 @ 8500 rpm and 700 torque. This motor is very easy to race due to the high rpm for max hp. We spin it 9200 thru the traps. It is a very happy motor.

When this thread started 2 years ago. I thought it was a great idea, and quite frankly I still do. I'm confused as to why we can have a 25 page discussion on one head, but this list never got any traction. I know I would appreciate more comparisons from the people with first hand knowledge of the strengths and weaknesses of each offering.

The Definitive, Emperical list of BBM Wedge Aluminum Heads
1.Indy Predator Non-traditional valve layout, once considered sacrilege is actually a major plus. Valves as long as your forearm. Pricing info anyone? Or is this one of those, "If you have to ask, you can't afford it upgrades".

2.B-1 TS The TS stands for "Trick Stuff" that you aren't smart enough to figure out. Like a Max Wedge, aluminum front end Dodge of the 60's, they won't even let you touch them until you have major racing cred already.

3.B-1 PSO Unlike the first two listings, I've actually seen a set of these, held them in my hands and inspected them.
It took twenty minutes in a cold shower to get my heart rate back to a manageable condition afterwards, but I survived.

4.B-1 MC I've had the opportunity to buy a few pairs of these, ported, used, for around what I normally give for two sets of Indy -1s.

I'll continue later, but the Wife just came home, and she's looking over my shoulder...
I considered starting from the bottom, more of my domain, but the the list of 210cc/ 70 cc stock knock-offs is getting very convoluted...

Not sure what you are asking Billy. The heads at the TOP of the food chain haven't changed and likely won't. Not enough interest and or market. So whats there HAS been there for years and hasn't changed. There seems to be a variation every now and then, like this rumored 600-13X, but it's still in inline valve wedge head and as such will be limited and can't compete with other brands spread port head.

As for the heads towards the middle to bottom..........flip a coin. Not much difference in any of them.

Being good friends with the Renteria's, during that period Tom,Mike,shawn and dusty got zero help from Indy with issues that came up building that 622" motor.... Those heads were done by Al Dixion (HRD ) and were worked heavily in the combustion chamber and ports..... those heads flowed right at 505 cfm 1.00" that was a number that Indy couldn't even get close to touching back then.. Russ and ken wanted to get there hands on those heads to copy for quite a while........

Hustlin Hoosier - That is pretty impressive. I have seen something about 600-13x but didn't really know anything about them.

SCATPACK1 - Thank you, I love it too

I thought TS stood for "Totally Serious". We have a 499 ci B1-TS motor that we tried running for a while. Because of the design and rpm it killed valve springs though. But, talk about some badass heads those things flowed 540 cfm. We were considering using a different block and making it into a 632 but probably aren't going to go that route. We might be selling that engine soon. Boatracer, yeah I remember all the trouble they went through building that 622. Sure is a great motor though. I would love to get it back in the Valiant someday if my Dad and I can afford it and get some things taken care of

Kenny,
Sorry if I have confused you and Monte...I have a tendency for tongue in cheek sarcasm.
I was trying to get a list actually started, hoping that we could get all the pieces on the playing field before we started moving them around.

What I was trying to point out is that even though many of these heads have been around forever, guys like me are fairly ignorant as to what it takes to put them to good use.

That Valiant may just be one of the coolest race cars on the planet, but I'm sure you know that already!!

Kind of lost this topic..., but I took the Brewers in to a flow bench. Have no idea about the quality of the porting done to them and not going to publish any numbers since they only relate to that flow bench, but they were better both on intake and exhaust than a set of ported B1 MC's and about 20% better than our previous "fully ported" 440-1's I had in the same bench previously. And that's with way less CSA.

They actually did have a water leak in the pushrod hole area that I fixed with some epoxy stuff but will fix it better later. Have not yet run the engine but will get it done and dynoed during next winter.

Here is a pic of the Brewer next to an Indy 440-1

Billy...I will find out soon if PSO's are worth the coin as mine just got back from Slawko's for the initial cnc work...Will be taking them and my current B1 engine to Glen & Kevin Self Racing for their magic very soon !!

Moving to PSO's is not cheap and is gonna be interesting to see how they stack up against my originals as they make some steam !!

Now that is a killer looking cylinder head!!!!!!!

Sanders 565 that is in his mustang is the single most impressive mopar engine running.

For that car to run that fast n/a is something to talk about. I don't think you can really call it a 600-13 head per se because of the amount of work that went into them. But you can now call Indy and buy castings. Send them to Goodwin and have them ported Don't know what to call them but in my opinion they are the baddest wedge Mopar head period and they make more power then any predator I've ever seen The guys at Best Machine have taken a great set of heads and put them to good use.

I have an nos set of the last production run brewer head. Pulled them out of the box and cleaned up the entrance to the port. Literally just squared the port. Under 10 minutes. With the 2.25 valve on a stingy bench head flowed 420cfm @ .650

Looking for any other brewer parts out there
