Well I'm definitely hoping I'm outta the woods now. Pulled the top end apart and took the heads to be pressure checked and magnafluxed just to be safe, installed exhaust cross over plugs. Then put everything together with new Felpro blue head gaskets. while i had it tore down, i went ahead and replaced the milodon water pump for a flow kooler one..... same housing, but new one has a billet impeller with more fins. had it running and sounds good, temps at their highest got up to 205-210. probably could use a better radiator and fans than the cheap $180 ebay stuff i have, but temps were way better and no boiling or compression in the coolant!
