I'm making pretty good progress getting the engine back together, but after installing the heads, intake and distributor, I've run into a snag on the fuel pump bracket. There are two studs coming out of the head that the bracket mounts to. They seem to be too long now. I can only guess that the machine shop removed the studs and reinstalled them but didn't screw them in all the way. They seem to be frozen in place now and I can't turn them with channel locks. I can probably stack some washers to get the FP bracket far enough off the block for everything to fit right, but if anyone knows how far these studs should stick out, or how to screw them in, please share. The parts manual shows nothing between the bracket and the head except the engine lift bracket and a couple of small clips.
