Bryanj:
Thats right Ken, i inherited a Van Norman and bought  an SPS. Both fit on the same table but cutters are different

eight0:
Ok I'll remove the pistons and see what they're like in the bores without the rings.

I'm at a loss for what to do here now to be honest.

eight0:
I've pulled the head again and checked the piston that was hanging up the most.

Without the rings it drops through. With the rings it's really tight, but maybe it's supposed to be this tight?

No, that is definitely not right.
Edit... Difficult to see on the vid but there appears to be a big gap fore and aft, piston to barrel. Have you tried that piston in another bore?

eight0:
It looks like there's a gap because of the taper at the bottom of the barrel.
Good to know that shouldn't be like that I guess. I was contemplating cracking the cases again. If I have to get more pistons and another rebore then so be it. I'm this deep in.
