2.2 w/ 108K miles: Top end or total rebuild?
 
I have a 70T with a stock 2.2 and nice tight Webers. Mileage is 108K. It smokes on startup and during acceleration (blue smoke). Question is would a topend only rebuild be a false economy at this mileage? I've heard that the early motors are not as stressed so the rebuild guidelines may be different from later motors.

Any thoughts?

Smoking while accelerating usually indicates oil getting past the rings.

IMO one would be better off rebuilding the complete engine rather than just the heads.
