So, after soaking on it for a few days, I wish I had bought new valves from day one. However, I think I'm going to go ahead and assemble the heads with the valves I have and leave the inner springs out for the cam break in. Reason being, before I can really even beat on the truck I am supposed to follow McLeods break procedure for the new clutch, although that's a whole other debate... I also need to finish building the Dana to take the place of one legged 9". Suffice to say, it'll be a bit before I get to really start beating on the thing. When the time comes to put the inner springs back in, I may swap out the valves worth a set of Ferreas. Until then, I'm going to try to keep making forward progress on the thing so I go back to moving it around under its own power and stop pushing the damn thing around. Lol.
