I'm going to continue this conversation by asking you if you know the on-seat and full-lift pressure of your valve springs. I've seen a bunch of brand new cams wiped out by starting up a new motor with stiff springs. Let's get this sorted out before you do your initial startup.

We need to address the proper procedure for startup too, if you don't know.

Have you adjusted your valves and you POSITIVELY know they are correct?
