318 LA rebuild after losing a valve seat

I wasn't trying to take a shortcut, I just simply didn't understand the importance.
And you know what?;
chances are very good
that if the cam is not out a tooth,
your cam will have fallen into an acceptable zone.
It's been said that 2* either way cannot be felt by your butt-dyno.
And I can add that my butt-dyno cannot absolutely feel 8*advanced from 4*. I could only tell by knowing what to look for ........ but the thing is I started out with 180psi,lol.
From 8* advanced to 4* retarded, that I for sure felt! and was remarkable to me.
