CNC Centroid Porting TSP/PRC LS7 Head

[thomashibbs]

I bought a pair of TSP/PRC LS6 Stage 2.5 Heads for my LS1; I lov'em to all hell. Biggest bang for my buck!

@thomashibbs what kind of gain did you see?

@pepene93 I gained 30 RWHP through an auto-trans + happiness and a beefier sound. I guarantee these heads would make more power with some extra fine tuning. my N/A cam is a little too big for my cubes, but these heads will work miracles once I put my blower cam and supercharger on. Worth every penny! PRC has got their $h!t down!

@thomashibbs did you have headers already? a good set of ls6 heads should probably make a bit more than 30whp with the right supporting mods. still sounds good. what would you say the total cost of the heads was?
