New best flow numbers for Edelbrock heads

U SIR - are making some EDELBROCK guys happy who were thinking of future porting etc !!!

Trouble is I can’t offer these numbers but I’m trying to hopefully find some 318-322 type of numbers At hopefully only a 200.00 upgrade from the 2.055. Those customers have to be willing to run number close to the 1008 bore size gasket (4.160-4.180) that bigger valve needs breathing room.
