Don't worry about the head gasket thickness, my experience has been that using the "standard" thickness gasket that comes in the gasket kits works just fine.
I'm not even sure if you can still buy the other thicknesses or not.
You should just remove the radiator and shroud assembly. Its easy and I think only 6 or 8 bolts to remove it.

So there is no damage to the valves or pistons, but I assume there are round marks in the carbon buildup on the pistons where the valves touched?
Or do you mean the valves did not hit the pistons at all??

we didn't see any hard contact it seems as the pushrods and rocker arms took all the force . we pulled the radiator and shroud but it looks as the radiator support has to be removed . the large sheet metal frame that holds the radiator is what we are referring to.
thanks again

Correct, I meant the entire metal end of the generator enclosure, radiator and all comes out with about 6 bolts. It looks like my description above was not accurate.
I'm not quite understanding how things got so damaged if the valves didn't hit the pistons.
Do you suspect the valves were stuck in the valve guides maybe?
I can't imagine how else you could bend pushrods and break rocker arms unless the valves were somehow frozen solid.
