Sealing rocker bolt hole on ported heads?
What are you guys using to seal the rocker arm hole on the ported heads. I've seen loctite and black RVT. If loctite, blue medium stregth or red high stregth? Which one actually works better at sealing and keeping the oil out of the combustion chamber? Thanks!

I've used black RTV, teflon paste, and some black non hardening "gasket sealer". All of them have worked great, the RTV seemed to be the easiest to clean off the threads if you are ever going to pull the rockers again. I would be afraid to use locktite on them, it would really suck to round the head off one of those rocker bolts or break it off in the head.

I would use Loctite 222 low strength threadlocker or Loctite 567 thread sealant. Both will allow easy removal and completely seal the threads.
RTV reacts with petroleum so I would not recommend this. Thread tape can string and cause problems if stuck on the intake valve seal (not sure if this would be an issue)
