I had a set of these rockers on my 4V closed chamber heads. The problem that I had was that I ended up having to buy adjustable push rods to get the valve lash adjusted correctly. Once they were set up, I never had any problems and put at least 50k miles on them. They were taken off last year when I upgraded to CHI aluminum heads, which had screw in studs.

Valve lash? Sounds like you were using solid lifters. This specific kit is designed for hydraulic lifters only.

Now these rockers - just the rockers - are also used with the stud (7/16") conversion. Is this what you had? I can understand a push rod length issue with solid lifters.

I'm confused by your post - can you clarify?

I have a hydraulic lifter cam, but with the piston on TDC and with both valves closed, the rockers were too loose. I know that with a hydraulic set up, you just tighten it down, but it didn't work for me with these rockers. It could have been my spring set up. They might work fine for your set up, but they didn't for mine without the adjustable push rods.

Thanks,
