lowering compression on 450

Ready for a top end job and I would like to lower the engine compression while the engine is apart. Machining the top of the piston sounds like a great way to crack a piston dome. What is the best way to go? Is there a thicker head gasket available? Or is doubling the base gasket a better way to go? Any experiences with de-tuning hyped up engines?

Doubling the base gasket is the easiest way to go. I have glued two or three together using the nonhardening Permatex

Base gaskets are to thin to do any good. Look to see thickness of your Hd gasket then get thicker one. Helps to know year and model when asking questions. Later George

Gary Gramer of Holeshot Motorsports will shave 20 thousandths off your piston like he did for Scott Summers. Wonder how much that would cost.?

2006 tc 450.

Why do you want to? Will this solve low rev stalls on hills?
