Cam
I would change the cam. AFR 185 heads offer some serious flow up to .550 lift. You need a cam that can take advantage of those heads. I don't know about the 351 bottom end you may have to notch the pistons to clear the valves. Take a look at the 165 head also. AFR 165 has a smaller intake valve and is designed to clear most stock bottom end with mild street strip cams. Always check your valve clearance though.
If its just a street car with some drag racing Call a major cam manufacture up and give them you spec and they will recommend a good cam. Comp and Crane are good to start with. I run a Crane 2030 in my 302 and it has a very good idle and makes power all the way to 6000 rpm. High lift and big duration cams kill a low compression motor. A cam thats good for a 302 is usually much milder in the 351 becuse of the extra displacement. get the 58cc heads for the extra compression. Look at the Air Gap Rpm to it may give up a little on the top but its an excellant all around intake. Match you intake, heads and cam as a combination and you will have an excellant performing engine.
Good luck
later Dennis
