CFR Performance HZ-9391-1 Compatible/Replacement for Oldsmobile Tall Steel Valve Covers - Chrome

Installed on a 71 cutlass (olds mobile 350 rocket engine). Fit perfect and look amazing. Intake manifold was painted gold to match original rocket engine color theme.

While these are beautiful, heavier-gauge chrome valve covers, they do NOT fit over taller valvetrain assemblies as touted. I have Harland-Sharp full roller rocker arms on Olds aluminum heads and the covers come in contact with them about 3/4" before seating on the heads!! Soooo, if you're looking for beautiful, heavy gauge chrome valve covers for your stock-valvetrain Olds engine, these are the ticket! If you have anything taller, keep looking. Can't beat the price, either!

Was looking for a cheap set of baffled valve covers that would clear stud style roller rockers on an oldsmobile. These worked fine. Would recommend.

I was looking for a slightly taller than stock cover to accommodate the full roller valve train while not interfering with the brake booster. These were perfect.

The quality is excellent for the price, the height works with a solid lifter cams exceeding .570 lift and Harlen Sharp rockers

there arent any holes
