Now I got in contact with west central div and I was all Ok with the thicker gasket.
So now that is cleared out, but..
From Pat C I got a mail today, and if that is correct understood he said he asked every full time NHRA tech official, and all have said it’s not legal.
If that was meant on bigger cam tunnels or thicker gaskets it’s not said, or maybe he mean both.
It's all very confusing.
Why is this not cleared out in the rulebook.

One wonder if roller lifters is coming to stock now 2020.
RPM from heads flow, free seats, free valevesprings, roller rockers, fat cams, more oil in pan, aftermarket parts and new rods/piston that handle it.

Dan Dvorak was years ago into put stock in specs of comp/cam and let rest be free ( not titanium ) and use a OEM intake but aftermarket heads to get it more easy.
