building a FAST legal small block

Belive it or not I have actually hand ported a few sets of stock exhaust manifolds with pretty good results,its a ***** but it can be done.One set was for a chevy with the crappiest manifolds Ive seen and it picked up quite a bit of power and changed the exhaust note.

I got a guy doin that to a set of BB HP ex.mans. Basically He's cutting them in half, and he's gonna dig em out to within a millimeter of there life. He'll weld them back together and then send them out to be ceramic coated. With what I'm paying you would think I'd be better off getting a set of TTI's... but thats the look I like and want. They should flow like the Niagra Falls after there done.
