I am having some issues getting my valve cover mounting holes aligned. I had trouble getting my Edelbrock intake aligned a while back and the advice I got on the forum to use thicker intake gaskets did the trick. I should have expected some issues with valve cover holes. I have Ansen short style aluminum valve covers and am planning to use studs. When the covers didn't fit on the studs, I opened up the holes in the covers from 11/32" to 3/8", using a drill press and just holding the cover by hand. It helped, but not enough. Right now, I have the top 3 studs in place and you can see from the below picture what one of the bottom ones looks like. I could maybe try going to 7/16" on all of them. I don't think I could drill off center very well using my drill press. Any advice?
