340 cam timing, 1.6 rockers?

I didn’t pull the cam out. Wishing I did before I re-sealed everything up and painted the engine. It always ran great, gave passengers whiplash, cylinders looked like they just left the machine shop, cam didn’t look wiped out. So I figured, don’t fix what ain’t broke and closed it back up. I did find that 2 cylinders had the rockers installed wrong so they had a bad wear pattern on them. So I needed to replace the rockers, which lead me down the hole of just getting some better heads. Funny how these things happen.

You really think I should tear it back open to see if it has some grind numbers on it?

Hell no. If you're happy with it, slap that pup back in and drive it.
