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.

I am a huge VORTEC fan...
But given that he is not trying to build a street strip motor... And that he already has the 462's, he will be out less money than going the VORTEC route... Don't forget the costs of a new intake and valve covers for the vortec heads....
Not to mention the "old school" cool factor...
