I have a 70 318 that runs good. I have to change the water pump and the intake ( bad carb, so I'm putting a 4bbl on ). I'll be changing the heads later when I find a good set ( with the right numbers ). Since I have to pull the intake and the water pump, I might as well change the cam since I'm half way their. I found that Hughes has a .489 In. and .520 Ex. cam that's on sale. Will this work with the stock heads ( besides changing the valve springs which I'm going to do )?
