Advice on Cylinder Head cfm for 340 stroker

moparodbuster said
Looking for advice on approximate cylinder head intake/exhaust flow reccomendations for my build:
340 block .40 over, 4.00 crank, 11:1@65cc pistons, [email protected] solid flat tappet, victor 340 intake, worked 950 Holley.
Going into factory weight '71 Demon w/ss leafs, 4:30 gears, reverse manual auto.
Considering...
1. Promaxx cnc: 285/195
2. Brodix cnc: 300/204
but some experienced advice before buying anything would be great.
Thanks

If the promax is real, that's the head you want.
Those flow numbers will keep you happy for years to come. You can make 550hp with the cam and everything that follows with those heads.
Any head flowing 140,200,250,275 from .200-.500 is a winner in my book, port volume dependent of course, 185cc is in the zone.imo
