hi john,
if the job is done right, you wont need shims. and will end up with a very nice engine.
ive seen plenty of home done flange repaires, were the old flange is NOT machined off. just the lip brocken out fully, and a new steel plate fitted. so the bearing can be pushed back further into the flange.
you should be able to measure the depth to the new flange with a vernier, and im sure someone will come up on here with the original depths for front bearings. from memory i have 1.611 thou full width bearing engines. and 1.555 for narrow bearing engines. BUT PLEASE CHECK.
turning the rods is a good way of checking white metal, like aways there are plenty who do this work, not so many who get it right.
kc is right pheonix cranks had early fitting problems, as far as i recall the problem with the web hitting front flange would have been corrected well before 1990. and is an easy fix, (grind and re-ballance). the centre hitting the cam however, only got worse. and wasnt corrected until 10 years ago. although that centre cutout is still out of shape today.
