And yes, I had all the plugs out so I could feel it better.
Wow, removed lifters and shimmed, removed rockers and shimmed, etc.
I would have driven to work and back to get the dial indicator. The time spent taking the motor apart and putting it back to together correctly is worth considering.

That said, you are close and should be OK, just don't float the valves with RPM.

Lol, it was already apart except I had already bolted the heads back on thinking I was going to use a smaller cam, but the bigger cam showed up Friday and the smaller one did not and probably won't until Tuesday or Wednesday. I really needed to get this truck running so I figured I'd give it a try. Didn't really have anything better to do and the drive to work is excruciating even at 4 in the morning so...But it runs great, I can't complain, but probably will anyway. laugh2
