Compression ratio...

Does a thicker headgasket increase or decrease compression ratio? I'm thinking since it's gonna be taller, it's gonna increase stroke and increase cr. Someone tell me if I am right and if not, let me know. Thanks.

Re: Compression ratio... (sandusky)

I'm probably wrong, but I don't think a taller piston would increase stroke. I understand the piston would end up higher, but wouldn't the fact that its lowest point is also raised and it just cancels out the increase up top leave you with the same stroke as before? It seems to me that a taller piston would increase the the compression by reducing the area in the combustion chamber when its all the way up. I probably wrong so don't flame me, just curious to how it works. Thanks
