I was wondering if the headbolts on the TPI 350 motors go through the water jackets?

Yes. If you are installing new head bolts use sealant on all of the bolt threads, otherwise they'll leak coolant.

Red Permatex has never failed me. Coat the threads 100%.

I used teflon paste, it seems to work great.

we used ARP thread sealer and all of the bolts on the outside of the head leak coolant. we do not see any coolant in the oil so we are not sure if the ones inside the head are leaking or not.

I've used plain old pipe-dope (available at any hardware store) for many years. No leaks.
