Will JB quick work as well as marine epoxy? Also I need to know if an electric choke needs a constant 12volts? ;D

Unlikely.

No. It needs switched BATTERY VOLTAGE which can be 14+ volts when the alternator is charging. Best to route power through an oil pressure switch so the choke doesn't heat if the engine stalls; and I prefer to NOT power the choke during cranking.

the connection to a standard oil idiot switch is a ground switch.
Are you suggesting adding a different type of pressure switch, one that is a true switch on with positive power?
Right now I am adding an electric choke, how much current flows thru that heater? If it is not much, can you take power from the coil ignition switch?

3-prong oil pressure switch, one prong like original to drive a dash indicator light, two as a "pass-through" (normally open) but when oil pressure closes the switch, the choke gets power.

You should not take power from the ignition coil if the coil has a ballast resistor. You could take power from an HEI power wire as the HEI uses battery voltage and a heavy power wire that can supply plenty of current.
Some folks suggest taking power from the windshield wiper motor; as it isn't powered during cranking, and doesn't have a ballast resistor in the circuit.
First Guess: The electric choke takes very little power.
