Then why does the Marion Stephenson/Don Forester 1980 Olds get to run screw in studs and pass tech? The engine in this car has been thru teardown many times with screw in studs and guide plates, never having an issue.
The "must retain OEM design" wording in the rule book was put there to keep everyone from switching to shaft rockers. You are allowed to switch from pedestal to stud mount. You are not allowed to switch from pedestal or stud mount to shaft mount.
