Motor was honed out and stock pistons were measured by machine shop and read as follows:

Piston 1 2.9922
Piston 2. 2.9926
Piston 3. 2.9924
Piston 4. 2.9929

All the bores read between 2.9940-2.9941

Clearance is

1. 0.0018
2. 0.0014
3. 0.0016
4. 0.0011

Nissan specs are 0.0009-0.0017. Engine is being built back to stock standards combined with a mild cam regrind from Isky, GX head and dual Hitachi's. Do I need to be concerned about #1 piston bore being out of tolerance that could lead to oil consumption or low compression?
