Rocker Arm help

I had the same problem you are having, same heads/rockers. I ran lash caps to make sure the roller didn't run off the valve. I ran like that for a season and a half without it being a problem. I will say that if you ever decide to put trick flow's on it those rockers are about a perfect wipe as you can get. They also work good on stock heads.
Good to know, I may hang on to them for when I get some Trick Flows or incase I ever go back to my J heads.

I am wondering if the chevy valves my engine builder put in these heads could be contributing to the issue? Because the stock type adjustable iron rockers (273 type) have great geometry on these heads. Also Mike at B3 says 1.6 rollers seem to have way better geometry in general.
