What does everyone reccomend/think? I'm looking at a set of Dart Pro 1 Aluminum 200cc intake runner/64cc Combustion Chamber/2.02x1.60 valves Heads with a mild bowl job and port matched. I think they flow like 198cfm stock, hopefully with the little port work, it'll take them up to around 250cfm. These heads will be going on a 9.8:1 388 Stroker Motor with a TPI Style Intake(52mm TB/Ported Plenum/ASM Runners/Big Mouth Baseplate) all with a Lingenfelter 219/219 .560/.560 lift cam on 1.6:1 Roller Rockers. Any other head suggestions?

Im not a Pro with this stuff but your combo is screaming for a Superram set up.
Why going with long tube runners?
Are you keeping it stock looking to a point?

If you can find a good porter, run your stock heads. Mine now flow like AFR LT1 Stage 2 prepped heads.

GTP are the Best! This is over agostino and AFR. you really should call Craig at GTP and he can quote you a price and give you some exaples of HP gain.

the ph# is on the site. No I do not work for them. I Just have seen some guy with LT1's and L98 get some SERIOUS muscle out of this product with a stock bottom end. The is a couple of guys with these heads doing 11's

Might as well stop there. GTP really is on of the best! That is why we use him for our heads! We try and only deal with the BEST products! For that, we are not always the cheapest, but if you get products from us, you don't have to worry about the quality.
Holy [email protected] that sounded like a commercial. I think I need a beer.
