Replaced head gasket because of loose bolts, (see and So It Continues part one) fire on rack connected to hose, runs fine good water out exhaust, unable to bring up on hose hookup, starts collapsing the supply hose.Today I take her out, fires fine, leave marina, on plane, port motor temp rising. stop. still have good water from exhaust. but block seems alot hotter than exhaust??? I have the thermostat out, I pulled and checked the sea water pump, Gen VI Big block,Stainless marine exhaust, original Thermostat housing 1983 454 version,Still have water circulating pump on engine, water temp gauge read 185, Starboard side(left) of the engine hotter than the port ?? What is causing poor water circulation thru the engine block? this experience was the same with or with out the thermostat installed Other engine runs 150 temp all day??

Behind where the sand was, is the casting rougher than everywhere else?Getting bad advice is unfortunate, taking bad advice is a Serious matter!!

08-22-2009 09:27 AMIf you got a partially torqued head hot from running once, it's probably warped. Did you do a minimum resurface on it?

Wow, never seen one like that before. I'd call the company that made the head and see about getting a new one. For all of the damage they caused, they should agree. After a severe overheating, you could have warpage, valveseats falling out etc.
