I'd probably start with a 0.035" gap and adjust from there.
I have Dart Pro-1 heads. i use a Autolite 3924 plug, gapped to 0.035". That seems to work well.

I'm running the Autolite 3924 plugs in my Roush 402. What do your plugs look like? There was a problem with the intake gaskets failing on the Roush 402s (happened to my motor).
