Reply to "Mysterious ‘China-wall’ gap"

hustlerMember

I tend to just lay thick beads of rtv on those gaps with no gaskets. Due to the variations using decked blocks, resurfaced heads, milled intakes. 1/4" doesn't seem that bad. The key is the bolts are threading with ease which it sounds like you are good on. The problem I recently ran into was the intake gaskets had to be elongated slightly on the 4 middle holes. The tops of these gaskets were bumping up against the valve cover gaskets. I have a sheetmetal intake that has a larger gap than my cast intakes, so I'm guessing the intake valley depth on the casting will play a part the degree of gap. See video below, I just don't have pictures of the gap variances.
