Whats hitting the valve cover the rockers or the poly locks? I have Comp Cams Ultra Pro Magnum rockers and they don't hit the covers. The Poly locks on the exhaust rocker hit the covers wouldn't let the cover sit down flat on the head. I used a 5/16ths thick gasket and had the 4 exhaust poly lock hex head cut to about half the original thickness now the valve covers set down and seal.
A friend had the big boxy aluminium rockers he had to grind a corner down on the rear rocker arm to clear the factory valve cover.
