    Default QD 21 1960 Johnson 10 head bolts

    I picked up this QD 21 and want to relace head gasket. I have 9 of 10 out but one broke. I cant find factory head bolts for this motor. I have the part number but none are available from any place I have looked including here. Can I just use hardware store bolts? The ones that came out are not going to take any torque. Should I use permatex aviation on the new gasket? Thanks for any and all help. Posted in the wrong spot and cant delete it last time.

    Just go to a hardware store and get a stainless bolt.----Why would they not take any torque ??

    The old ones are almost bare of thread except for the part the goes into the block from rust. About 3/4 the thickness of what they were originally. Looks like they would snap right off if I give them any torque. Any thoughts on the gasket sealer?
