Can anyone tell me what the spec measurements are for doing the Valve Lash on this engine. Thanks for any help you can give.

Wasn't sure if I had the manual on my laptop (I do now), but Google is your friend

Pages 49-50

VALVE CLEARANCE (ROCKER ARM-TO-VALVE TIP) SPECIFICATION
Intake Valve . . . . . . . . . . . . . . . . . . . . . . . . . . 0.35 mm (0.014 in.)

Hi MarshallPowerGen, thanks for the information. I downloaded the manual and everything I need is there. Thankyou, this is very much appreciated.

How much space is there between the top of a piston and the valves at TDC on a 1995 John Deere 4039t?

Deere does not list the thickness of the cylinder head gasket at all so an accurate answer to your question is difficult.
If the following dimensions (shown in the 3 screenshots below) are all in spec, there should be no issues with valve to piston clearance.
Specs below from Deere manual CTM8.
