The Right Valve Covers

I had Comp pro magnum rockers on my 360 with Mopar perf. valve covers and didn't have any clearance issue using std thickness gaskets. They had the screw on baffles like flyfish described. You definetly want baffles. The mopar perf. covers were on my car when I bought it and they didn't have baffles and slung oil out like crazy. I made a set from sheet metal because at the time I didn't see any listed. That solved the oil slinging problem.
