Camshaft swap

How much the ratio drops from a thicker head gasket is your homework to do which a compression ratio calculator, like at the Wallace racing site is a huge help.
Cometic gaskets are pricey but get the job done. There excellent gaskets made to your spec. .060 thick? .022 thick? .100 thick? Just tell them, they make them.

If your on the fence about putting money into it due to the engine swap plan, I say skip it all and focus on the swap plan. Save money!
