440 build working with what I’ve got

UPDATE:
I have been able to upgrade to a set of ported 906 heads with oversized valves, shaved .020, swapped the stock iron intake for an edelbrock dual plane at the moment, may keep trying to trade that up to a single plane and have acquired bearings. Should I order some thicker head gaskets to ease the compression a little bit, I don’t mind burning premium but I’d rather not have to buy race gas. It’s slowly coming together! Thank you to everyone that has helped so far! I’ll be getting with Killerslant soon to do some more swapping and see what we can figure out!
Do you know what the compression height is on those pistons ?
Should be 2.029
If you have a .060 thick gasket you'll be 10.50ish compression. That's assuming the heads are now 84 cc chambers
