GM Performance Z06 SCCA Heads. Any dyno results? I've read through earlier posts on these heads, but there isn't much info regarding performance increases after installing these heads. Does anyone have any dyno numbers? Also, what cam are you using with these? I am particularly interested in these heads matched with a streetable cam like the LPE GT2-3. Thanks.

Re: GM Performance Z06 SCCA Heads. Any dyno results? With the GMPP LS6 CNC heads from Pace, I dyno'd 380 rwhp/405 rwtq w/a Comp 216/220 525/530 114 on 91 octane.
Super midrange, xlint manners on the street.
My car is a 2001 Z28 A4 w/3000 stall, FLP LT's w/cats, 3.73's.
Since the install, I've added underdrive pulleys, !FRA and a have a cutout on the way to extract a bit more.

Re: GM Performance Z06 SCCA Heads. Any dyno results? Thanks Early Man.
The specs on the LPE GT2-3 cam are similar to the stock Z06 cam, except more lift and slightly longer duration.
Z06 204/218, .551/.541, 117.5
GT2-3 207/220, .573/.580 117.5
Any cam experts out there that can tell me what differece in performance I could expect to see versus the comp cam that Early Man is running? Assuming all other things are equal can I expect better? worse?

Re: GM Performance Z06 SCCA Heads. Any dyno results? These are the ones that are ported/CNC/milled 0.055 etc by LPE for GMPP...sold by Pace, SDPC etc.
Went with the Comp because of the strong midrange and decent idle (114). Power strong to 6300 as per the dyno sheet.
Just swapped out my 3000 Midwest for a 3600 Vig. Now have to hookup with a group of "racers" and get to the track.
