I found the problem lol my allen keys were grabage, they were hand me down keys from my dads auto shop, i thought they were good quality keys but i gues not, went to a hardware store and got myself some good quality screws, and the screws in the cooling head came right out
now i still have the problem of the screw thats stuck in the crankshaft but im thinking im just gonna replace the crank shaft and if i ever need the old one ill find a way then to get the screw out :P
