Im probably wrong here but.
Doesn't the longer duration camshaft events lessen the effective stroke (where both valves are closed)? And this is where the motor hits it powerband?
So with less effective stroke don't you have less air to compress and is why some cars run so well with a lesser duration camshaft because they do have a much longer effective stroke which increases cylinder pressures.
So wouldn't a deciding factor be how much cranking or running cylinder pressure a setup could handle without popping a head gasket.
Small blocks I know are different.
Im a bit confused on the "If" you nailed zero deck? With the proper tools or a good moch up checking each end of the deck then deck the block to achieve a zero deck "with consideration to piston rock" its easy to achieve zero deck.
I see many just taking a block in to have it square decked and cut to the oem deck height which to me is hit or miss at times.
.032 on a true zero deck small block has worked well for me to 7200 area.
Id think a BB has a bit more piston rock and would not go that tight on quench.
Its possible at least on a small block zero deck with a modern domed piston to still hit a good quench # on the pad.
Factor in the al. head aspect and the heat lost couldn't you run 110 or better on track and at times if needed non eth. premium?
And does that seem reasonable as when running on spray, some have a separate cell with the C116 to handle the increased cylinder pressures that nitrous produces
