Spray is a part-time thing, likely less than 1% of the total time you're going to operate the car. The other 99% of the time, you have to operate on pump gas without detonation. The program for that, with iron heads, is around 9:1.

You do not increase static compression ratio by porting the heads. You may increase BMEP, but not SCR.
