Hi all,
im in the process of rebuilding my f20c and am deciding on what pistons to go with. I am interested in this set of Arias I found that are 87mm 11.5:1 CR, but the description states that they are .040 proud of deck. I understand what this means but am unsure if this would force me to have to use a thicker head gasket or not. The description also states that the 11.5:1 CR is when used on a stock head/block. I’m assuming this means stock head gasket as well but thought I’d ask here if any one knows otherwise.

Thanks!

Awesome thanks !
