Been creeping on this forum for a long time, recently decided to join. I went to replace the thermostat on my 1990 140 looper and broke every bolt that hold on the thermostat housing, on both heads no less. The previous owner i guess removed the thermostats and did not put grease or never-seize on the bolts upon re-installation.
After trying to extracts the bolts with zero success, and being told by a machinist friend, the heads are garbage now. So I need to find two used heads. There are numbers stamped in the head, 333686-2 for port and 333686-1 for starb.
I've found one decent head on ebay with the matching number, but my question is... Is there another number I should be referencing to find the heads? Does anyone know if they are the same casting? Are they side specific? In my parts manual they are given one number which is 0398818. The thermostat housings are in good shape so I only need the heads, and gaskets I guess (i haven't gotten that far yet in research). This is a great motor and I am or course PISSED that the guy didn't do this properly, and on top of it there were no thermostats so god only knows how much damage I have done by running it with no tstats.
Any and all help/ advice is appreciated. Or course now I'm scared to take of the heads in fear of breaking more bolts.. The motor might just be totaled at this point, but I would have to say that if its true.. Please help!!
