Does this include the camshaft and valves? Just wandering if this includes the camshaft in valves, if the ones in my current mustang will fit this if it doesnt, and if that which ones i would be best off with if im planning on adding a supercharger down the road.

  • The heads come bare, meaning they have the valves installed along with the springs but you need to provide your lash adjusters and roller followers from your old heads, or you can get new ones using the Ford Racing kits M-6500-M50 - lash adjuster assembly or M-6564-M50 - roller follower kit. The factory camshafts will fit without issue but I would be looking to upgrade to better camshafts if I were to do heads as well. Don't forget that you will need assembly lube for installing cams, lash adjusters and followers. I used Comp Cams assembly lube #103 as per Comp cams instructions.
