Default Plug Gapping on a Lump series 1 chevy 350

Hello all,

Once again I come to the wise men for advise on my 73 conversion. I am replacing the spark plugs but have no idea what to gap them to.(OR if I should gap them at all) I know there are some things that matter, i.e. compression, etc. So I will give you what I know. If you could tell me what you think the gap should be, I would be grateful!

Chevy 350 bored .60 over
9.6-1 compression
last used autolite #26 spark plugs
pistons hypereutectic 4.060
Edlebrock 600 cfm carb
electric choke
performance HEI ignition and wires

You mentioned having HEI ignition, not points and coil.

0.045" gap is standard.
