Canton fabricated valve covers part#65-206 brand new, never used. They would not clear my roller rockers (Comp Cams pro magnum 7/16 full roller 1.6 ratio) according to my engine builder. I did not have him attempt to clearance them, I just decided to try to sell them. He said the notch for the alternator was where they were touching. Canton sells for $225 and makes them to order (I waited 4 weeks), I'm asking $180 shipped.
