Re: Head bolts
Probably really depends on the manufactures recommendations.
Best to consult the service manual for what your working on if possible!

Re: Head bolts
I found a manual online (one of the ones that has bad print) and it says use motor oil on threads

Are the holes blind or do they go into water passages? If blind holes I'd use copper antiseize. If in water use liquid Teflon. It will both seal out any water and will keep bolts from seizing up.

Re: Head bolts
They are dry holes. The manual i found online says to use oil, but I put a dab of never seize on them

I agree. Dissimilar metals don't play well with each other.
