Anyone running the Procomp fabricated BBC valve covers??

[prostreetC-10]

Well the 454 fell into my Camaro with no issues at all! I'm just not real comfortable with the 1/8 inch of room between my tall vavle cover and my stock booster. I love the look of the fabricated covers and the BBC ones have the tops tapered which would buy me some needed room. Problem is that I am very familiar with the quality of "most" of the proform products. They are supposed to have billet rails but it wouldn't surprise me if the holes didn't line up. What has been your experience? Thanks!
