EQ heads, Chevy rockers and what studs?

I set up a set of the Hughes Magnum rockers for member Matts440 when I did his Eddy cylinder heads. With a solid roller that has a fair amount of lift, the rockers still had to be raised a bit for proper geometry. Anything with less lift would need more correction. A longer valve would make it even worse, and just using a stud conversion just puts you back where the OP started from. Overall though, the Hughes are probably the easiest to correct, at least on a Magnum head, and they use a cup style adjuster.
