A word of caution here:
I have known people who have installed valve covers and after the engine was
in the car been unable to remove them do to clearance issues.
I do know that the Comp Cams Pro Magnum roller rockers have a smaller
profile than some of the aluminum rollers and do fit under my cast aluminum
valve covers without any spacers... and I run a cam with .597 lift.
