Dutra wasn't using studs in this book. His example engine was a worn out '70s(?) engine.
When I did the valve job 2K miles ago, I found Red Permatex smeared way up the head bolts. I used the same to reassemble. This time, the machine recommended a Permatex Blue #2 non-hardening for the threads.
Yep - mine too! Before the head shave, I calculated 8.0:1. After removing .750" off the head, I'm at 8.6:1.
