0.002" is way too tight for a race engine.

0.007" is more typical for a race engine. I lot of flexing occurs under the high stresses in a race engine.

Also, please check the end play with JUST the upper bearing in place, then again with JUST the lower bearing in place to confirm the alignment of the upper to lower bearing halves.

You know the saying, "If you have too much bearing clearance you are the only one who knows. If you don't have enough bearing clearance, EVERYBODY knows."

It's best that you are the only one who knows.
