I have found that my Crower stainless roller rockers, if swapped from stud to stud will give a different alignment with the valve stem. I took two rockers and set them up with a cut Chevy guide plate then welded them.. Went thru both heads, when I came back to put the other rockers on, they were off..

I used Comp guide plates, several sets differnt seasons and they all seemed to be built the same, but rockers didnt line up.

I believe T&D rockers when installed address this issue, but with a rocker shaft you have to watch that the roller tip is paralell with the vavle stem.. more issues.. Wish they would perfect the solenoid valve actuators. Then use a computer to do the bump stick work..

I had an issue 2 years ago with the Comp Guide Plates on my Merlin Heads. Pushrod guide plate on number 7 broke for the exhaust valve. Thank god I didn't drop a valve. Replaced the guide with a stock GM pushrod guide, the roller and replaced the valve and I was good to go.

After that happened I spoke to the guy at my machine shop and he told me that he had a lot of problems with the aftermarket guides and swears by stock GM pushrod guides.
