If your engine is 8-bolt (74 or 75) that is a viable option.
The late B20F (8-bolt) engine was the trial run for the B21 and following
lower ends. The main bearings are the same but the rod bearings and rods
are different as are the wrist pins, compared to the earlier 6-bolt B20.

The B21 standard bore is 3.622 and the B21 standard pistons and rings should
work admirably in an 8-bolt B20 bored to this size. The BIG problem will be
getting a big-bore headgasket. IPD may have one and some of the swedes may
have them. If not, copper gaskets unlimited in Phoenix can make you one.
