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?
