HELP!! 440 Distributor, Head Clereance

I'm pretty sure the mallory unilite will take that module but verify to be 100% sure. The unilite works with EB rpm heads. My unilite doesn't have vaccum advance though
Guys, need your help i bought a pertronix distributor and found out my edelbrock heads and distributor dont fit. I had to grind a little off the head to force fit it. Do any of you guys know of a distributor preferably billet that can use my pertronix ignitor module, and uses vacum advance and mostly fit??
