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.

To add to my post above #51
I went with the magnum roller tips and gaped at true .030. On the studs I had my heads done with screw ins that look like the stock factory studs and the towers/bosses won't have to be milled this way. Personally, I'm not jamming the crap out of the engine ALL THE TIME, but when I do...I'm not worried. I have the race type studs with the guide plates put away, but I'd want to get another set of heads to not mess up my originals IF I ever use them. I run the 140 cam as well as the 30/30 with 4.10's and an M20. The M21 I was using always made the damn car rattle and shutter when I let the clutch out. I'm talking shake here.
