Belongs to this dyno sheet-
Specifically the 537whp pull. This is the spec of the car though I failed to mention the 3.5" ETS intercooler originally-

Stock port head
GSC S2
Speed density
Kiggly valvesprings

More logs to compare. This is an 87x100mm 2.4-
More or less the same setup as before but substitutes an FP Black for the turbocharger and of course the larger motor. This car also has a Magnus cast intake manifold which has always seemed to be worth an extra degree or two of timing since the improved VE keeps knock away.

Here i found a timing map tuned on e85, 28psi gt3076r, 9.3:1 stock displacement:
The timing numbers compared to the EVO's are so different, is this a product of much greater flow of the EVO heads?

I am wondering do you happen to have any camshaft specs? If I had IVO/IVC, EVO/EVC, lift, centerline, etc. I can do a lot to calculate BMEP. Between the fact that it seems there isnt much getting into the cylinder to create cylinder pressure (i.e. small valve), you stated they dont flow, I presume an inefficient cylinder head. This is the 20v or is this an older 16v head?
Since we have less to work with we create the pressure with more timing. An Evo really doesnt have this issue since it has a very effective cylinder port (even factory), 34mm intake/30.5 exhaust using the 85mm bore.
What is the load factor of 9.2500 translated into a boost number? Looking in that column at least it looks closer to what I would see in an Evo...though maybe a little more timing out the top.
