Default PTV clearance question?
I am building an LQ9 with PP stage 3 heads and 2.08/1.60 valves. I am putting my Vengeance VRX3 226/228 585/588 114+4 cam in the motor that was removed from my CTSV. Do you guys think that I will need to fly cut the flat top pistions with that size intake valve? They are 317 heads with welded chambers to 64cc and not milled any at all. This engine is going in my 2005 RCSB Z71 GMC with a 3000 stall. The truck will have longtubes and full exhaust with no cats. Thanks.

It looks like you might be OK but I would at least clay it to make sure.

I think I would be OK. But wanted some better opinions than mine.

Measure it. Don't take some ls1tech know-it-alls word.(Not directed at anyone in particular.)

.080 intake, .100 exhaust is usually minimum.

Good answer. Don't have to clay it either, just use the soft spring method!
