Default Bellhousing Dowel Pins
Removing the dowel pins will not fix your problem. The holes in the bell housing are off.

The best fix is to drill the dowel pin holes in the bellhousing .015" oversize, get a thick (.125" or more) washer ream the id to the dowel pin od. Bolt your bell housing to the block without tightening the bolts. Install a dial indicator on the end of the crank. Rotate the crank to find the bellhousing offset from center. Tap it into place with a hammer and tighten the bolts. Check one more time to be sure it has not moved and slip the reamed washers over the dowel pins. Weld the washers to the bellhousing.

You are done and your bell housing will now (and forever) fit correctly!
