You need to machine the top of the rocker for the nut to set on, the rockers are never flat and it f**ks up the threads when you tighten the nuts tight. As said in other post you need to run a tap through it.
Yes I tapped them without issue. I didn’t lock any of them down tight. I mainly just wanted check my pushrod length and make sure they all threaded in easily. Well. That didn’t go so well.
I didn’t get far enough to see where to machine/flatten the rockers as seen in other posts.
