My valvetrain is loud (ticking/tapping) after installing gen 1 1.9:1 rockers, mls gaskets (.010 thinner than stock), 105 lb. springs, and ported heads. I am not sure how much if any was taken off of the head surface. My question is: is there a limit to how much you can take off before you have a problem? I am at least .010 plus whatever the heads were decked thinner than stock. Ed M suggested I replace the lifters since they have over 100K, and I am planning to do that, but I am wondering if I have anything else going on...
thnx
