Offenhauser Dual Port 360 - run it or scrap it?

might I suggest; lol
This is just a question;
Small Closed-chamber Alloy heads, a solid lifter cam, and something like the tall KBs that need to be machined, to set the cylinder pressure to around 185psi. This should run on 87 gas.

I have a set of Speedmaster heads for it, probably going with a hydraulic roller cam, something like Howard's 710525-10 or Hughes SER3034ALN-10. Gonna call both before I decide, ability to run on 87 pump gas would be a plus but I'm OK with running 91 if it would let me make a decent power increase.
