I don't like using the cork gasket, after scraping pieces off the head for what seamed to be forever, I'll never use them again. Even if a gasket set says no sealant, put plenty of RTV on both sides. Like John said. -Smoky Mt Frank- In a message dated 3/29/2010 7:34:59 A.M. Eastern Daylight Time, johncgg@xxxxxxxxx writes: I am in love with the center bolt valve covers on the El Camino. They never leak. The P/O put an older style 4 bolt 350 in the Monte, and they seep all the time. (Just like the old ones on the Elky did). If the factory ones are straight, then use them, just put RTV on them on both sides of the gasket, but clean the heck out of the surfaces first. That is the only way I know how. If they aren't stright, then put them on something straight, and hammer them in to submission, then get some of those heavy metal strips that spread out the pressure. That worked for me as well as anything, but the perimeter bolt valve covers always leaked on me. Good luck with the project! Anything will be better, right?
