Looks like your cam lobes were polishing the inside of the valve cover
The cure for that is stacking two gaskets together to add a little more clearance

But probably didn't need to with the 1X andrews cams. Scotty 1974 Z1A 1015 welded Z1 crank Andrews 1X Cams Delkevic 4 into 1 The following user(s) said Thank You: SWest
