Yes, be very careful about which bolts go where, you can get into Big Pain if you mix them up. Also, those bolts are shouldered. They are only tightened till they are snug, you dare not try to seal it by tightening it more, you will only snap expensive things in the cylinder head if you do. When I thrashed with this the culprit was an old shriveled gasket - see my photo below with old and new. Also, there are two styles of sealing gaskets for those bolts - smaller thinner ones that work with the 79, and larger thicker ones for teh 80, 81, and 82. That's another gotcha that gotme.
Once you verify that the cover is flat, clean that channel within an inch of its life, smear some threebond in it and set the gasket. Put a pea-sized dab of three bond at the corners where the cam end caps are - the round end bits on the gasket that have a nearly 90-degree bend. Then put the correct bolts in the correct spots and only tighten till they are snug, and no more. If it leaks after that, your problem is elsewhere.
Also - remove the tach drive when you do this. Breaking that is also expensive and painful.
You really really need the FSM.
Welcome, by the way!
