why worry about compression when you can put different pistons?

There ya go now you can run 11.#:1 or 12.#:1 compression on pump gas.

There is no diff betwen the 2 head casting
The only diff that youll find is going to be, cams and exhaust springs if its B18b or B18a or B20b or B20Z all have diff exhaust springs... B20 and B18 intake cams are not exact the same.
Have the head shaved by .020 and youll raise the CR by .4
Have fun...
