im not sure about milling. living in california i want to keep the compression below 11:1 and to save money most likely GM gaskets.

the engine will be in a 69 camaro with no emissions.

If Gm Gaskets And If Using The Special Tsp Stage 2.5 5.3l Heads With Reesesed Valves Then You Should Use The Stock Size Pushrods

Btw That Would Be A 10.9 Comp
