Tonight i finally got some time to install the main bearings and take some measurements. Originally i was going to use plastiguage but i broke down and bought a set of mic's and a dial bore guage set from summit.
From my understanding of how this works, i first take a measurement of the crank journal i was about check using the mic. I then took the dial bore guage and attempted to find the smallest measurment on the mic and then zero'd the dial bore guage. I then torqued the main in 10 lbs increments until they reached 110 lbs. I inserted the dial bore guage and again looked for the smallest measurement... That number is my clearance.
I only measured the first 4 mains. Below is a pic of my numbers.

My book talks about using plastiguage and says .002-.003 clearance "to be very good". I just wanted to make sure that my measurements above look ok. Another question i have is that the bearings are not perfectly round, if i take measurements closer to where the bearing halfs meet i get a diffrent measurement.. Still with in limits according to the .002-.003 limits.
Here's a pic of a main reading .0020, the papertowels just kept the dialbore guage lined up while i shot the pic

Another Q, the dialbore guage is leaving these marks on the bearings, is that normal or should i be lubing these up first?
