Are your planning to leave the rest of the valve train stock? It seems like a good idea to update the rockers, maybe like
these Comp Cam rollers. It wont keep me up at night without the O stamped originals on there.
The press in studs do create some anxiety though. They are original and cool but it seems worth the 'loss' to keep my original 302 in one piece. Am I worrying about nothing here??
I'm likely going with the Comp Cam 12-107-3 (3849346 replacement). My '69 has an M21 and 4.10 gears. Both of these have updated internals.
