I went with AFR eliminator LT4 210cc competition heads for my current setup. I think these pieces were really nice. They are being run out of the box (no mods at all), but were not bolted on right away - my builder wanted to measure the sprigs himself and re&re, and did find a little bit of crap (shavings?etc) to clean out. I bought my heads from TRE performance in CA. Good guys. They seem to move a lot of AFR product. The guys at AFR know them pretty good.
Reaper how do you plan on running 11 or 12:1 NA now and then going to a TT down the road? If you are planning for a lot of boost in the future it sounds like the heads you go with should be large chambers (65-70cc+). I guess if you found the right pistons you could bump that CR up now, but you'd have to then swap in blower pistons later. If you are going to achieve 11-12:1 CR NA with crazy dome pistons do not turn a blind eye to piston to valve clearance. The NA cam you pic would obviously factor in huge. When I was piecing my setup together I didn't even think to consider PTV clearance - I should have...

I am going to give AFR a call today and hopefully we can come up with the best head for my build whether it be LT 227's or SBC 235's/245's. If I need the converted I will give AI or Clayton a call to see who will convert them for me. I also need a solid roller setup with Jessel shaft's, Morel Ultra Pro Hippo's, Pushrods, and a beefy Cam. So I am hoping one of these company's will be able to help me out. Either way I will be making a decision today.

If I we're going to the trouble to convert heads, they would be something more capable than out of the box AFRs...
Why not a set of Allpro 23 degree with a badass CNC job, or 15 degree CFE heads that have cracked 1,000 HP N/A on 358 cubes...
Don't limit your options, it's only money.

Yeah no records here. I am not a hardcore dragger, I only want to build a strong street setup and I don't think I need more than what has been stated. I am only shooting for 1000rwhp on the dyno but will tune it down for the street 700-800rwhp. I will however have that tune waiting on a flick of a switch if I want it. My car is a mildly used street/show car that see more highway pulls than drag pulls. No reason to go overkill on the car. I will however check out All Pro and see waht they have to offer.

"Only" 1000hp? That's it? That car will act like your average Civic on the highway, and probably get similar MPG, lol. I'm willing to bet 750 to the wheels will be more than enough to deal with 97% of anything you'll run into on the street.
Only 1000whp? The amount of LT1s making (or have made) that kind of power can probably be counted on one, maybe two hands.
Sounds like you're very ambitious. Hopefully you've got a deeeeeeeep wallet.

I talked to All Pro a few minutes ago, seems like just the heads will be around $3,500. I have to call back tomorrow to talk to Bob and he will give me an exact quote. I may stick with AFR since the whole head and valvetrain setup will be around $4,000. My pockets are not deep enough for $4,000 in heads alone.
I am waiting on AI to give me a call back on the valvetrain and cam so I can place my order there. I also need to get ahold of JE so I can figure out a piston for the build. I will be placing a order for the crank and rods through Flatlander, main caps through Competition Products, and then some parts and hardware from Summit. I already ordered the Strange S60 for the rear end and I need to find someone for a tranny. All and all I am starting to get on the ball with this. When I get all of my parts together I will start a build thread to document everything.
The fastest 6-speed LT1 is only running 200cc Ai LT1 castings with a tiney 218/218 cam along with an eagle 355 rotating assembly. No fancy parts just a well thoughtout and quality setup. 1012rwhp and 156.7mph in the 1/4 in a 3680lb car.

Is he running turbo, charger, nitrous, or combo with two of the three. Those are damn impressive numbers. Where can I see and find out more about this car.
