Ptv issues.. Turbo 5.3
Stock rotating assembly, new bearings head studs etc, I'm looking at getting the tick stage 2 turbo cam. I've got a Garrett 7583 turbo I'm putting with it, and I haven't found a deffinate answer whether the stock heads/valves will interfere with their cam. 219/223 .61x .61x. Just got my heads back from the machine shop and they took off 10thousanths to resurface them.. I'll be using ls9 gaskets as well.. Any help is appreciated.

What heads do you have? My 5.3 with 862's milled slightly to get a flat surface and tick stage 2 turbo cam had plenty of PTV clearance but the 862s have the 1.89(?) intake valve where 799/243s have a 2.something valve, doubt it would matter tho I bet you're fine
