Besure to measure the diameter of your pistons. I just recently replaced the head gasket on my '50 C. It has 3 1/8 in pistons in it instead of the orginal 3". I had trouble finding the correct head gasket. The 3 1/8" head gasket assumed that you were working with a Super A/B/C and that you had a water pump. The holes for the water ports are much smaller. Ended up drilling out the holes on the gasket so that they matched more closely the holes in the head/block. The head bolts are torqued to 80 ft-lbs. The manifold to 20 ft-lbs. The valves are set to 0.014 in. After you get it running again you need to warm it up and then re-torque the head bolts. This requires you to remove the valve rocker arm and re-set the valves. While you have it apart clean all of the carbon build up off the head and the top of the pistons. It would be a good time to check for valve wear. I was able to push on the valve stem and give it a quick visual. Not the most scientific but at least I didn't see anything of significance. You would also want to take a good straight edge and check the top of the block and the head to see if they are warped. Cleanliness is next to Godliness. There was a post yesterday that suggested using brake parts cleaner to wipe the surfaces of the head and block. Some kind of gasket sealant will help to keep you from doing this again. Some use the spray on kind. I used a high temp silcone sealant. Which ever you feel more comfortable with. I am sure that I have missed a couple of things but this gives you some things to look for. There was also a post yesterday about oil flow to the rocker arms and not using a locker washer on the center bolt. That would be worth reviewing. Good luck.
