yeah, if you've milled out a bcp head that much I'm almost surprised it hasn't cracked. overlap doesn't burn exhaust gaskets. poor sealing is the main culprit, and ****ty gaskets is up there as well. the rubberized/metal clad gaskets always worked the best for me on 8v stuff. the paper felpro type gaskets (or dimpled paper/metal) are absolute gutterslut trash.

^ well it's running now, I used the exhaust gaskets in the elring kit from FCP, metal over paper I think? I did buy new turbo manifold washers and copper nuts from Ian. I haven't driven it yet though just warmed it up to set the timing.

I drove it in to work today, I swapped in a B cam, long story short the threads for the cam gear stripped out of the ipd cam. It seems more linear and less laggy but maybe down on power a little bit. Still, blasting out of the tunnel up the hill in 3rd put a big grin on my face :-)

He said they burnt a piston at the drag strip, pushed the piston out, pushed in a new one, sprayed the cometic with engine paint, slapped it back together and kept making runs.

Dry and clean. I'm using a cometic on an o-ringed block and it went in dry and clean.

That's fine the first install, some of the viton went away so I supplemented with Hylomar for the second time around.

We used to use the copper gasket spray paint on the copper head gaskets for the AH Sprite and to seal the passages we would add weather strip adhesive. That was at the track to fix a blown head gasket. They didn't make Cometic gaskets for sprites or Volvos back then.
