What are the actual stem guide measurements? I have seen them put back together with new seals and a fresh valve job run smoke/trouble free for years. For the thread repaiir:
I don't know, I don't have small bore gauges to measure the stem guides. Looking inside them though there is certainly uneven wear marks and some galling inside the guide.
I looked at those E-Z Loks, however they are hollow. Wouldn't I have a potential issue with coolant coming up through the threads unless the valve cover bolt threads were completely sealed?
