Re: Afr 215 Raised Runner
IMO the 215RR is the best 23º head you can buy for the LT1, short of converting a gen 1 head.
I put a 355 together with these heads that made 493 rwhp 452 lbs-ft after a lot of tweaking. This is through a dana rear and zf 6-speed and using a moderate hydraulic roller cam.
With a solid cammed stroker, I think the heads can probably go 525-550 rwhp for max street/strip type car. At that point, I'd switch to a better cylinder head and a little less cam to stay streetable and make the same hp/tq. If you need more than that... then there's nitrous. Either that or just do like I am and switch to a gen 1 small block of monstrous proportions.
BTW, what are you doing for an intake manifold?

Re: Afr 215 Raised Runner
Sure haven't Jason. I e-mailed him a while back and it bounced back. All I can say is... the guy was very busy last I saw him and I guess he's still going strong. 
That's business..... the successful end of it anyways.

Re: Afr 215 Raised Runner
I just went to the AFR website for a look see at these. I'm a bit fuzzy though. Would you have to run a custom manifold and/or custom headers?? The pricing list states that "no LT4 plug angle available" yet these are stated as LT4 heads.
Just trying to clear some things up. Thnx.

Re: Afr 215 Raised Runner
Yeah as MG said they are nice heads to run.... OTOH you could convert a set of All Pro's or 18x Brodix and still run a stud mount rocker. You would still have the same issues with intake manifolds (since you should run a single plane or sheetmetal) and converting a set of heads over can probably be done FASTER than getting a set of AFR's.... this 2 months wait crap is annoying for castings.

Re: Afr 215 Raised Runner
Why chase big block numbers with a small block unless you have to?
I say get a tall deck BBC and go with a 632ci and you can get 900 hp out of that easliy. It will be much more streetable. It is usually alot cheaper too.

Do yourself a favor and hunt down a few single 4-bbl (cast intake) race engines. The first one you're gonna look for is a 434 ci small block. Then, a 632 BBC like you mentioned.
I think you'll be pleasantly surprised to find that the price difference is ~$10k.
With what's available today in castings/cranks/etc., you are not going to build a raised cam, tall deck BBC for less than a 427-454 cid SBC. Aint gonna happen.
As for "chasing BBC numbers", what are those?
Would you say that 650-750 hp NA is BBC numbers? What about 150-200hp more than that?? What if you could make ~750hp @ ~7000 rpm???
Very feasible #s for a BIG street small block with the right induction. Throw a nitrous system and more fuel to the mix and you're right there where the best NA street BBC's are with alot less weight and more room to work.
Don't get me wrong, I like BBC's as much as the next guy but for a sports car that isn't entirely drag race and maybe does a little twisty driving... I'll take the small block.

Re: Afr 215 Raised Runner
Fastbird,
Yes, you need an intake that matches the 215's raised runners. No custom headers are necessary. Although, for building an engine of this level, I'd surely recommend them. Most off-the-shelf headers don't have enough primary length for my tastes and I've seen dyno tests (with my own eyes) where engines gained a good deal of avg HP & TQ with nothing more than an adjustable collector. A custom also lets you take advantage of something like a merge collector.

I 100% agree with the header statement, I just wasn't sure if it was a standard header pattern that we LT1/SBC guys are used to seeing.
Thanks for the info. Food for thought for my next motor.

Bret,
When you order All Pros's make sure your check book is fat.They quoted me over $5000.00 for a set porting and assembled with my springs and they weren't converted to reverse flow cooling.
Get what you pay for,Huh.
Beautiful,LARGE flow numbers and casting's and if I had it to do over I would go with their 23* set up.
