OK, a couple of simple things first: what do the plugs look like-is one oily black?? You started with about 90# comp on all and new gasket is less, is the new gasket thicker?? that would do that. If one plug fouled it misses and can sound like a 'chuff' BUT spitting oil out of the exhaust is an over rich diesel thing not a gas engine thing so that is the real problem. Oil will foul the plug fast. If #2 or #3 then it could be the oil passage to the rocker assy leaking past the gasket. You now have the cranking problem--Is the starter jammed to the ring gear?? try gently turning the engine backwards to release or loosen as Red Dave suggested. Its also possible that a valve is jammed open blocking the piston, this can happen on re-assembly if one pushrod did not seat in the lifter-it holds the valve too far open. I just replaced the head gasket in my A and know how easy it is to have a pushrod not seat. I suggest you pull the rocker shaft again and try cranking, (just enough to make sure it turns as all cylinders will be against pressure or vacuum and it won't want to turn easily), IF you find that was it, I suggest you pull the head again to make sure the valves and piston top are still OK. Better now than later since if you don't find an obvious problem at this point you would have to pull it anyway. If you do find the problem then just re-install everything, clean the plugs and try to start it-if it starts and runs ok you're done. Good luck.
