Thanks for the help John. I was hoping Id hear from you on this.

My current heads are 34mm intake SC heads ('80-'83) with all new valves, springs, and retainers. Everything is stock since I never expected the engine to rev past 6700RPM with the GE40s and the 40mm Webers. Do you think of running the GE40s with MFI and the bigger ports will change anything drastically? Where do you think this engine will stop making power now?

I kind of fell into this MFI setup after I had already sent my heads off to be rebuilt and I'm re-engineering the top end as a result. Now the heads need to be disassembled, ported, and tapped for MFI (~$800), or I need to sell them and start over with a set of early SC heads that already have the 39mm intakes (~$???).
