I removed the old head gaskets (Fel-pro) & garbaged them. The picture attached is of a Fel-Pro head gasket #8264 PT-1, a set I purchased several years ago. Actually have two pair. I test fitted this gasket & placed the head over it & it is completely covered by the head. I do not remember there being the extra upper inch with all the horizontal holes. Maybe I am juts getting old! Comments?
