Dd why say its silly and take it to a shop then provide info on options? Id give it a go
Agreed, I meant to say that it is silly to take it to a shop [when it can easily be done at home]. I have no power tools and do all my own Datsun maintenance. I have not taken my Datsun to a shop since the 1980s.

Here's a trick used with British motors and motors notorious for getting stuck on head studs. Yeah head studs but I imagine the same principle can work. Put motor back together but leave the head bolts slightly loose. Run engine till head moves or gasket blowout. If that hasn't shocked the bolt free of any binding rust then fell free to do the other stuff

Heres a tip from an old mechanic. As I have had to deal with many rounded head bolts over the years I have found this to work a treat. For obvious reasons, a single hex socket is best. Put some corse valve lapping paste on the head of the bolt before attempting to loosen it. The valve lapping paste will help it bite really hard into the bolt. It washes off. You don't want any of that stuff inside your engine though.
