I believe the trick flow 190s will be a top contender for a head with stock pushrod location. Camshaft in my opinion should be in the 600 lift range.IMO and if you're going to all that trouble maybe compare an air gap RPM to a Victor Jr and put that to rest.
The TF vs the Shockers will be a good comparison. Similar port volumes and CSAs. I expect the TF to have the upper hand in that one, but both will be running out of air well before 6,000rpm. The Bloomers should make power a good bit longer.
As far as manifolds, I would love to see all kinds of comparisons. Air Gap, TF, Indy, Victors. It's the time and money thing again. If the rpm gets pushed to 6,500 and beyond the Air Gap would be toast against the single planes. We're trying to push the heads to the limit, so single plane it is.
I would like to see out of the box manifolds compared, but most of them are cast with 340/360 cid in mind and will choke a 400+ inch motor. That's why the Victor 340 and Super Victor are ported. The two Victors were chosen because of price, availability and the fact that they are both pretty good manifolds.
