Thread: Rect. vs. Oval

Tweet

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?

I'm at work and don't have my cam #'s. I did forget to mention that this is a motor in my 19' V-drive. As far as machine shop prices, they vary, but a comparable set of cast iron heads out of the box might gain better performance for the price. I'm assuming The 049's don't have hardened seats or bronze valve guides, as they were designed for leaded fuel, I'll need new valves, springs to match my cam and the labor. Are you saying I'll see no HP gains?
