any one here has 1:6 rockers that hits the valve covers. I have a 94 camaro z28 with the new chrome red bowtie vavle covers. My car is missing pretty bad after a high rpm like 3- and up. My rockers seem loose. I'm checking it out this weekend but does anybody have that problem.

 

If you don't have Crane rockers they can hit the valve covers. Trim down the support beams.

Make sure when you tighten the rockers you tighten down the lock as well. Make sure you aren't tightening more than 1/2 tunr past zero lash.

 

I bought the lt4 hot cam kit and these rockers came with the kit. Are they crane. I really never paid atten.. They should not hit. I think there loose. Becuase there very very loud. They should be quiet

 

GMPP LT4 rockers are made by Crane.
