408 stroker head gasket recommendation

My W2s are closed chamber iron race heads .
I run 9.7 comp and my cam is a 246/250 on a 108. No issues … I think the TF chambers are as good or better so they should support high 10s compression.
The quench will be the trick . You could install .050 gaskets instead of .020 and get more detonation if you lose the quench. That iis why mid 70s 440s with 7.8 true compression still pinged under load and heat .
