Do you guys have a receiver groove in the head for your wire O-ring?  I am thinking the only way to hold that much boost is O ring groove and copper gasket.. The small block Ford crowd has pretty good luck with Cometic style gaskets but none are available for a Y block.

yes we have grooves in heads, but that wire was blown away with gasket. Cometics could be done for Y-block too, but cost will be too high for individual. Believe me, we have asked them...

Is there is a reason you are not using a copper head gasket with the wire?

Tried that but water went in wrong hole whatever we did.
Maybe its time to try again...

That video of the car from the rear showing the launch is scary when that freeze plug comes out.  Some of the circle track engines I work on have a strap across the freeze plugs to keep them from blowing out.  This might be easier than tapping the freeze plug holes and installing screw in style freeze plugs.  There are some different varieties of screw in freeze plugs with some simply being a straight thread with the plug having an O ring and another variety being a tapered pipe thread which simply needs a corresponding ‘thin’ style pipe plug.

When you use copper every water passage has to be sealed with a bead of RTV on both sides of the gasket or it will leak.. I think copper is your only option for holding that type of cylinder pressure.. I use copper and O Rings on my Lincoln Y blocks and it took me a while to figure out how to seal up the water leaks
