bearing clearance question

i currently have a .020 crank. i am using acl .020 bearings and my clearances are .0015. if i use a .019 bearing with my clearance be .0025. this may sound like a stupid question i just want to make sure my thinking is correct before i waste another 180 on bearings.

its a 6.0L that is turbod going for 1000 fwhp.

If that is an iron block I would go with the .025 and make sure I had a good oil pump to move lots of oil through the bearings at that power level. The .015 might be ok on an aluminum block and less power.
