the pink gaskets didn,t work on my victors either. plus they tore after I took the covers off the first time after first passes to redo lash. went back to mr gasket black cork type, rtv.d to cylinder head side. worked for years on stock heads and cast valve covers. will see longevity on this set up. don't think pink gaskets are the problem, the identified mismatch at the cylinder head is the source off the problems. why eldebrock built the victors this way????
