Just so we're talking apples and apples - a set of '462-type castings will flow around 185 CFM intake with 1.94 intake, as high as 210 or so with 2.02s. A bit of touching up may increase that a bit.
A stock, out of the box set of Vortecs will flow around 235-240 CFM...25-30 more...and cost significantly less than rebuilding a set of stock heads - and WAY less than rebulding and PORTING a set of stock heads.
For a 283, not a big deal, I agree.
