GM HEI mopar dizzy hybrid

I know we have been here before, i am doing the GM HEI module upgrade to a 1974 Mopar V8 electronic distributor. Got some cool ideas and such that i will put into a buildup/modify thread when i am done.

Heres the question. When y'all swap in GM modules, do y'all just run stock modules?

Have any of you run the performance modules instead?

Looks like theres one by moroso, pertronics, and Accel.

If so how much better than the stock modules were they?

Also any of you swap in lighter advance springs from either mopar performance or mr gasket for a faster mechanical advance curve?

Thanks in advance
Matt
