I have a 2000 ls1 with ls6 intake long tubes and true duals the engine is in a 1991 Firebird it has no cats and all emisions devices are removed. I am thinking of going with the gmpp 88958665 cnc'ed heads I am having trouble deciding on a cam. The car is a weekend driver and road corse and auto cross occasional drag strip. Right now I am happy with the 6200 rev limit so I want to gain below that limit. I am open to others heads as well the car weighs 3200 lbs has 3.41 gears and a M6. I am willing to spend the dollars for the best combo so give me some oppinions please.

look at air flow research heads,or trick flow heads,or Texas Speed PRC heads.get a fast intake.you can get a cam from Patrick -G.vengeance racing ,and Texas Speed sell good head/cam combos.
