Hughes rockers

How deep is the threaded portion of the hole in your heads? I'd bet that aluminum heads like Edelbrocks are threaded deeper. So you didn't have enough shims on two studs and ran the nuts down on the shank? Why not just cut the studs off and move on? One thing I've learned in hot rodding is that are few true bolt on's, most need some tweaking.
Agreed, not much aftermarket Modifications "bolt on". For me it's just easier to throw a couple washers on top and move on then cutting the ends of the studs off and boogering up the threads and trying to make them nice again but again like you said I'm moving on. I guess my point was that if hughes is doing hundreds of these kind of applications it would seem like if 50 out of the 51 heads were having this problem they would say something? or if Edelbrock heads have deeper hole compared to stock heads yada yada....
Also part of my point is that every paper and page of instruction says if you have a problem to call them and I did.
But in the end all is well that ends well and the reason I'm saying anything is to make sure no one else has this problem and misses something. Hence the forum helping each other.
moving on ......
