I would remove both valve covers while the engine and check the valve clearances. Since the gap will close about 0.001 to 0.002 when the engine is hot. This should tell you if there are any major issues. If 5 & 6 don't have any gap you know what your problem may be.

After ensuring that every valve has a ballpark correct clearance, run a compression check. If 5 & 6 are still bad, then you'll need to pull the head and examine their valves & seat. You can use Prussian Blue to get a good feel on how well they should be sealing.

If the compression check is A-OK, fire her up and recheck while running and readjust as necessary.

Good Luck & Keep us posted
