I've got an 04 gto that these are going on. I'm going to put PAC .650 lift beehives springs on them. When I was reading earlier it said that the 02-04 with lightweight valve had longer stems. Do you guys know if I'm going to Have any issues with this setup and a torquer v.2 cam. .595/.598? Thanks you guys.

^ unshaved, you'll be fine. It's the duration that could create PTV issues. I'm running 04 243 heads now with those valves. 228 duration with .639 lift.

Thank you. Ill check my duration but I don't think my cam is that large. Any ideas towards the duration limits? I hope mine don't exceed yours lol.

TV2 will fit if heads not milled, you'll need to measure for pushrod length.

^ Grab a push rod length checker to be double sure it's correct. Take the measurement and add .050 - .075 for lifter preload.

If those are LS6 valves, they do have longer stems and that IS why you really need to measure to get proper preload.
