New Build Trickflow 190 and quench

Good Afternoon. This winter we plan on doing a stroker with one of the early 70s 360 blocks that we have.

I have already ordered the Powerport 190 heads and I am going to get the single plane intake when it arrives.

So this is the build I have planned

PowerPort 190 heads and intake

Now when I purchase a rotating assembly unless I am thinking wrong or overlooking something because these heads are 60cc the only way to create a quench without having more then 12:1 compression is by having the heads opened up is that correct?

The reading I have been doign it looks like I can get away with around 195 cranking pressure with an aluminum head but I don't know if that can be done without a quench. So Far I have looked at ordered a flat top piston scat kit and running a thicker gasket.

A .080 4.06 gasket is giving a static compression of 11.5 and a dynamic of 9:1. This is at sea level which is pretty much right were I am.

A .080 4.18 gasket puts the static at 11.2.

So I guess I am asking what are some thougsh on quench and compression balance and what some options might be.

Thanks a lot.
