Now to put together the H beams I have here into my spare na block.

That head should be fine if you just smooth out the sharp edges. Do the same to all 4 chambers and have the head shaved.

Damn Mike, that's nuts! Or screwy?

Glad I put a little locktight on if I ever pull the plate, but still, wouldn't help with the snapped shaft...

If you don't mind spending ~$200, that head could be fixed if it's just the chamber that's beat up.
I wouldn't even tough the roof of the chambers, just clean up the quench pads.
A little welding and some die grinder action, and a then get the head surfaced.

I've fixed much worse damage than that.

Sounds like I will be taking this head to one of the local shops then and seeing what they quote me to fix it.

I'd send it to culberro...

Local shop are mostly joke.

Sand down the top of the piston, shave the head and run it. (if it was a stocker )

Reminds me of when I re-installed a IC pipe and a piece of one of those little clips that hold the hose pipes in place broke off and got sucked into a combustion chamber. Same damage. I had the head welded to fill the damage and surfaced and threw a new piston in that hole.
