What hp and torque am I making?

I have not found a standard type of replacement head, which would be along the lines of;

Edelbrock
TrickFlow
W2 - W5

That is to large ether OOTB or well ported, NOT race ported, that’s different, that is to large of a head for a 340 or a 360. I should also state that, on a combo that’s not out of wack or insanely disturbing in the parts choice.
