oh shit Rod.... I wish I had seen this earlier. It's out my way but I know two guys, one of which is beating up on AFR's aluminums with his ported/flowed cast iron chevy vortec's... Total cost brand new----$800 but that's for a small block. He's even better with BBC heads....... Especially aftermarket aluminum heads. PM me if you'd like the number for either one. The other guy is equally good, he just doesn't sell new parts, only works on what you bring him.
