12mm(?) double hex for the cylinder head bolts. I got a 4 piece tip set from Pep Boys for ~$10. The tips fit in a 1/2" socket. If you plan to get a 603 engine, you'll have the 10mm(?) tip for that too.
If the head gasket set is more expensive than the head gasket and manifold gaskets, then just get the pieces. The exhaust manifold gasket is 5 of one shape of gasket and 1 of another shape of gasket.
There's a hose from the idle valve to the intake manifold that's a PITA to replace with the engine in place. It's much easier to get to with the head and/or intake manifold out of the car.
How old are the distributor pieces?
How old is the water pump?
