Unless your first name is Merlin I doubt tuning skills will matter much at close to 11:1 -- especially when Rhoads lifters are added into the mix.
If it were mine and I was set on using those heads I would run the Cometic gaskets, but would go with .120 thickness and say to hell with worrying about quench. We concentrate on the bottom side of the danger area with quench and want to stay under .050" total to avoid detonation, but the far side is anything over .080" the danger also goes away. Short track guys in my area have gotten away from the D-shaped dish and found more power in an open dish. I'll give you that at off-idle power might be down, but there is probably enough swirl in the chamber at mid to high RPM to make loss of quench a moot point. I would take the bet that a thick gasket and standard timing is going to make more power throughout the powerband that an engine that has to be band-aided with massively retarded timing.
