I really doubt C foam will help you compression unless your rings are completlly gunked, it really just frees up fuel lines, I had a 70's model beater and tossed some Marvel Mystery oil into it, and clean out the oil lines, and it evened out the compression, it worked for a while but not a rebuild in a can - some people are 100% against the mystery oil, so check into before you just do it.
