Hey all, my b20 block is trashed (headbolt threads are non-existant so helicoils don't work either), and I have a spare b16 laying around (needs to be bored over cause the walls are scored from broken ringlands), now I have the crank + rods..and would get oversized CTR pistons (.2mm over). Would i need all new bearings and would this be more trouble than its worth swapping stuff over? cause I would have to swap stuff over to a b20 block anyways.

thanks,
mike
