cylinder pressure and dynamic compression with different camshafts`

building a solid roller 416 stroker motor and i was wondering about cylinder pressure and dynamic compression and what i should shoot for. wanna run it on 92 octane pump gas. is a 416 with heavily ported iron x heads. looking at the horsepressure article on hughes they shoot for a 165 cylinder pressure with iron heads which put me at 10.5:1 compression and 8.17 dynamic. so is this what i should be looking for or what compression should i play with. inputs are 8 cylinders, 4.070 bore, 4 inch stroke, 6.123 rod length, 10.5:1,63 degrees abdc and 1800 altitude
