You didn't mention which cam you have. The 049's are a good oval port head. Exhausts are nicer than most ovals. No gain in HP but you will move your torque and HP bands down to a more reasonable range to make you happy on the street. If you are going to have head work done, I wouldn't mind one bit that a set of 049's went on any big block for the street. By the way, are your machine shop prices that high there? 2000?
