Depends on the year engine. No one gap is correct for all years this engine has been made. Typical spark plug gap is .035 on points type distributor and .044 on an HEI type system.

A/C plug # R45TS and it gaps at 0.045 That is the factory plug.

The correct spark plug gap does not depend on which plug you use, it is dependant on what engine it is installed in. The same plug can be used in many different engines, and each engine might have a different gap specification. Instead, you need to ask something like: What is the correct spark plug gap for a 1993 Chevy 350 engine? (or whatever engine you have).

A 1965 Chevy didn't come with a 350 and HEI. Best guess would be to use a spark plug for a vehicle that came with that engine and ignition. If the engine has iron heads, it probably needs a tapered seat plug. A good starting point would be R44TS or R44T(with washer) if not a tapered seat plug. For plug gap, try about .045".
