I know their are tons to choose from but.....wondering what recomendation ya'll have? I know they need to be 14mm but other than that I have no idea what would be a good choice.

Edelbrock heads 80cc Keith Craft
Edelbrock RPM Performer Intake
1966 Cast Iron 427 S/O block
Static Compression ~11.3, Dynamic ~7.7
Holley 850CFM Carb.

Thanks,

I’ve been using the Autolite 3924’s with the MSD 6AL for years with very good results.
