The Right Valve Covers

I'm running a set of Hughes rockers in my 360 and have a set of Holley (M/T style) valve covers that clear. I massaged the tin baffles for the oil breather and PCV to be sure they wouldn't hit.

I did have a set of the cast Edelbrock valve covers and did some clearancing on them, but it was for the end of a rocker shaft that was hitting and not the rockers.

I would think that the fabricated-type valve covers would work well, but I don't have any experience with them.
