PrecisionPorting heads made awesome power
with Bobs stage 3 ported & polished heads, comp cam, Z06 intake, 125 shot of Nos, and a few other little mods, plus a tuning by LG Motorsports My car hit 517.1 RWHP on the dyno. This is 120 hp more than before. I'm Sold on PrecicionPorting. Bob was a lot of help and you won't beat is price and quality. why pay 2,200.00 for heads when you can get the same results from PrecisionPorting heads.

Congrats on the dyno numbers, Lou and his team at LGM are one of the best in the business!
Do you happen to have the air/exhaust bench flow test numbers, or perhaps any other data on your particular heads so we can compare them with the so called $2200 ones as stated?

Heads are 67cc cambers, intake 216cc, Exhaust 80cc, flowing at 295.5 intake & 224.9 exhaust at 0.5500. I had the heads milled and the cam spec are 222/224 566/568 12. There must be something right I gain 120 hp over my last dyno run it was 397 rwhp.
did they spray it on the dyno

They are a supporting vendor, and the link is on the left with the other ads. I think it is under "head porting". They have been very popular on the C4 sections, and Bob has run 2 GP's, and a has a great rep. for good customer service.
