Pushrods damaged

By the way you describe it, the pushrods seem to be rubbing excessively against the guideplates, correct? That could mean bad guideplate adjustment. By the way, you are using hardened pushrods, right?

how can u adjust the guideplates? they only go in one way, at least the ones I have and seen. Only thing i can think of is of theyre not hardened pushrods about the wear problem. is it just a few pushrods or all of them? If u got the time just put in a new timing chain and sprockets, i dont like the timing gears, and I have one, they sound cool at first, people think u have a blower, but Really sucks with the hood open, just too much racket and is a pain to find a vacuum leak or rocker tick etc.
