All this timing and valve adjustment confusion is mind boggling. This used to be basic stuff that any high school drop out could understand. I can't tell if those are flat top pistons or not. I would check the deck height and if it isn't 0 decked I would ditch the thick head gasket and run shim gaskets like the factory did. If it is 0 decked then those Fel Pro gaskets would be perfect. Maybe the cam installation should be double checked so might as well see what's under the timing cover. If the dots line up it should be close enough to run fine. Degreeing the cam is the preferred way if you have the time, especially if the cam is unknown. If the cam is unknown I would seriously consider doing some cam shopping. Then adjust the valves, drop the dist in correctly and enjoy.
