Default Sealant on rocker support bolts?
Are you supposed to use a thread locker or sealant on the rocker support bolts? I think they might be a source of oil leaking into the intake ports.

If so what type did you use?

Of the port job on the head shows the threads for the rocker arm bolts, then YES. Otherwise stock, they're a blind hole.

I use either ARP thread sealant, or RTV Ultra Black, whichever I happen to have on hand at the time.

This is your correct answer.
