I will try to answer
The 2.0 engines used sodium filled exhaust valves that expand more than non sodium valves.
The gap is determined by the expansion rate of multiple different metals
The type of actual valves and actual pushrod materials in your actual motor will determine the valve gap you need to use... that will play friendly with the amount of expansion when the motor is warm
Is is safe to assume then that in the absence of any info on the materials of the pushrods/valves on the newly built engine that we use .006 gap for intake and .008 gap for the exhaust?
Yes
Safe to assume
Did your rebuild use chromoly push rods or large mm stainless steel valves?
Is it’s a 3 bolt head (2.0). I would assume 6 and 8
