Roller Rocker geometry questions

Lots of theories here but the bottom line is this "that is as good as it's going to get with the Crane golds" Every set I've ever used on eddies and iron heads has this exact same problem. If it is the 'bad' valve job etc. etc. them why isn't there a problem with Hughes rockers and lots of others.
And as far as 'fixing' it with lash caps goes, you will still have the same problem but it will look better because you will be looking at a bigger diameter. The roller will still be off centre the same distance as it is now.

My advice run it as it is just like thousands of sets of Crane golds run and that is 'a little off centre'.

As far as your studs go they are wrong, you need the 'EDDY' ones or W2 ones
