Rod and Main Bearings and Pistons
 

I took my block and crank to a shop and he called me today notifying that I need to order .020 Rod bearing and .030 Main bearings and suggests that I should go .030 or even .040 over on the pistons?

Does anyone know who or where I may be able to get theses parts at these specs?

Thanks.

Edit:
I have 7MGE, with no plans to go turbo. Just want dependability.
