Also are you using the correct plastigauge?
Spec is 0.0008-0.0021 in. for production and 0.0008-0.0025 in. for service.
Looks to me that you're not reading the plastigauge correctly. For instance, for a 0.002 reading the squashed portion of the plastigauge should fit completely inside the red section of the 0.002 area. The 0.003 reading should fit completely inside the white portion of the paper gauge.
On the package of plastigauge it should have a working clearance printed on it, do you have that handy?

Well chances are you will get lucky. I know guys that have been building engines for years and have been lucky most of the time.

started the truck yestrday ,it was in a coma for 6 weeks !!
drives good just dies when slowing down under 12-15mph to turn or stop at a light.
as for any thing else i noticed som good torque gains on idle to 3000rpm with part throttle ,cant step on it just yet , breaking in the new bearings/piston rings
every thing else is great
will tray to post some pics
