What feeler gauge should I use for a cold adjustment. It's a rebuilt engine and I need to do an initial setting on the valves. I am thinking adding .002 to the .014 and .008 to get things rolling. This sound right?

Yeah-Don't second guess the factory. You will need to warm it up and reset anyway. Set it to spec, run until warm, reset to spec. Don't over think this.

My thoughts are that it is cold and that the metal hasn't expanded yet so therefore I would need to compensate. From what I can tell here I don't.
Thanks.
When I run tools in an well down there beyond 10,000 feet, I expect a length difference of 1 meter or so due to thermal alone - even more in a geothermal well.
This is an f, or 2f engine right? Not an extremely close tolerance, tempermental, high tech, race bred powerplant......
I wonder if Toyota set an initial adjustment, then went back and adjusted after warm up?
When the lobe is spalled as shown, it erodes the bottom face of the tappet. This cause rapid increase in the valve clearance. Even if the valve lash is tightened back to spec, there is a significan loss of valve lift and duration, so the engine will feel very lazy. starting & idling is not adversely affected, but WOT operation is degraded because the cam becomes the airflow limiter instead of the carburetor.I just finished stripping down an engine from a spares vehicle, '76 2F unknown mileage. Bottom end OK looking top very sludgy, cam badly worn and ALL the valve clearances 0.15 to 0.2 at least. I never ran the engine, it was incomplete and had sat for a long time.
I was wondering how the engine would have run with such wide gaps, poor power, poor starting, could the sludge be a result of low running temps from the clearances? Anyone ever had an engine like that running?
Picture of the cam below.
