273 Rockers on a 360

Hi all...yes, I will be clearancing the inner radius of the rockers so they don't touch the spring caps. They were clearanced before, but it doesn't look like they took enough off. As the rockers push to valve down, it actually gives much more clearance. So the tightest, or lowest clearance from the valve cap and the rocker is at installed height. This will be taken care of.

The issue I'm trying to fix the most is the sweep of the rocker across the valve. I believe this change can also fix the push rod rubbing on the pushrod guide holes. My question is, does anyone have instructions on how to correct the sweep, or is it done by trial and error with shims under the rocker arms on the pillars? I've see the sweep patters on roller rockers, is that what I should aim for on these rockers?

I will do a sweep pattern of what it has now and then will see if I can shim it a bit to see what I can get. Trial and error.. :)

BTW...Yellow Rose...I bought the heads assembled and I don't know the stem height, or if it's longer than stock. It could very well be...it has a 205 intake and 165 exhaust....
