View attachment 768117View attachment 768117 Got my 512 stroker almost together, but the top valve cover bolt holes aren't lining up! And Couldn't get the welded up aluminum covers to fit either. The rocker arms were too close to the gasket flange. Tried some chrome , stock shape (MP?) covers and they fit pretty good, other than the 2 top holes being misaligned. Will try to enlarge the 2 top valve cover holes tomorrow. Any ideas?
