RapTR PTV Does anyone know what the PTV would be for a RapTR CAM on an 02 LS6 with stock heads?
I bought the TRex but I'm thinking now it might too close on an 02 LS6. I believe the LS6 in 02+ had a smaller base circle and GM put in longer valves to compensate.
TIA

Having longer valves has absolutely nothing to do with PTV clearance. It may change the length of pushrod you may need but that should always be measured anyways, just like your piston to valve clearance. If you already bought the Trex throw it in, degree it to the proper intake centerline and check your piston to valve clearance. If you don't want to pull the heads than use a checker spring with a dial indicator.
