HELP need heads for a G5X3
What are the best heads for the G5X3 in a 01 SS m6.
AFR 205
PRC Terminator 200cc
Any other PRC head 5.3, 5.7 , or 6.0 any stage
This is for a friends car, with g5x3, lid, ls6 intake, spec III, pace LT, cut out, 3.90 gears, nx 150 shot..
He doesn't want to upgrade to a FAST 90 intake yet, so what would be the best heads for this mismatched setup , for now??? The AFr's cost more but would prob help out more, than the prc.. But if the afr's have to have the intake to perform , then maybe the cheaper prc's would be better.
Thanks for the help
Feel free to post your setup's and dyno numbers

I would go with the TSP 5.3L 2.5 Heads. Smallish 220cc runners with great flow, yet small chambers for good compression. You need to decide if he's going to flycut though, you may need to go with the TSP LS6 Heads with stock valves. But I would maximize the combo and flycut.

Well, since it's one of the cams designed to get the most from stock heads, I went with Livernois LS6 heads and couldn't be happier. But as for not flycutting... once your heads are off, you have it apart enough to flycut. In other words, it's no extra work on the motor, so tell him to not be stupid. Flycut so that he can properly mill the heads and get the most from his setup.
