I'm Building a B16a for a customer of mine with JE pistons,Eagle rods,and a set of ACL bearings. I've always used stock bearings with the moters I've built so I dont know if it's necessary to check the clearances with a plastigauge because they dont make differant clearance bearings.

Lookin for advise from someone like Earl who sells and uses these on a regular basis.

 

You still need to plastigage them to make sure the clearance is within the specs. Not an easy fix to change the clearance but never have had to do that yet.
