BTR3 and Heads Question Have an 05 LS2 GTO, just installed the BTR 3 cam, LS7 Lifters, and Thompson Motorsport CNC 243 Heads with Stainless valves, .660 BTR valve springs with the 0.041 Gaskets. Do I need to change push rods? TIA

I would at least measure for correct length, especially if the base circle is different &/or if you milled the heads. You are working with a bunch of unknowns, so pushrod length is an unknown too.
