vortech heads. if you can use an aluminum intake, the edlebrock performer for vortechs. Scoggins has the heads for $320 each after the spring/retainer upgrade. They also have these in combo intake/heads for a discounted price too.

If your really pinching pennies, I think if you search hard enough you can find L31 vortech heads used from the salvage yard for $100 each. You can easily spend $200 in machine work and spring upgrades for them though so it might be worth it to buy new.

If you have to run cast iron intake, use the z-28 high rise and have your vortech redrilled for it to mount up. Assuming you can use that one if not get the cast iron marine version of the vortech intake for $169 or so. If you want to go nuts spend the $500+ on a brizinski intake. Not legal for our class, but if engine claim is your only rule then hey WTF.

If you can't run headers, use the vortech manifolds off of big trucks and suburbans. Or vette centerdumps are good too.

do you have a compression rule or not? double humps or vortecs are gonna be the best bet

look on mortec.com or do a general search for gm casting numbers not all camelbacks are created equal. if you could find a set of 041 castings or 041x casting they are very good. but i agree that for your money the vortecs they are talking about complete for 300 something is hard to beat.my only other reccomendation is the ho 305 head great compression and torque and easier to find. im drawing a blank on the casting #'s i have a pair laying around 601 or something ill find out and post later but u still would want a valve job and some decent springs. if u go the cheap and easy route build it to make low end power and gear it accordingly its cheaper and lasts longer than trying to turn 6500 all year. i found them they are 601's and i think 416's are the same but i know the 601 305 headr work good 1980to1985 z28's whole casting #'s r 14022601 and 14014416. i know many guys othe than me that had good results tith them just dont over cam the engine

the 416s flow better than the 601s if you run the 305 heads.

I have checked both & also checked the 187 heads..... those were really poor.
