I though about using anti-seize, but the wp bolts into an aluminum spacer (that also houses the thermostat) which is bolted to the block. When I removed the w/p bolts, coolant came pouring out of the bolt holes. So, be cause of that I did not really want any anti sieze compound circulating through the cooling system,
