Head Studs aren't really needed with the 7.3L's
If you know you have a blown headgasket. Fix that problem, as it maybe the cause to your possible miss and poor running engine. If you still have the rough running engine then we can trouble shoot it.
Before you tear the truck down, scan it for codes. Being you have a possible blown head gasket I do not know if an injector contribution test would work very well. This test would tell you if you have any bad injectors.
First off lets trouble shoot the possible blown head gasket. I suggest you do a compression test on each cylinder before you tear it apart. Something is pressurizing your cooling system. After you do the trouble shooting for the blown headgasket. Then do your tear down and inspection. During your inspection use a straight edge to check the head for warpage, look for cracks new the water jackets, especially near the exhaust valve, since you have the heads off might as well have them machined and do a valve job to them.
Then assemble using quality parts. Also check the uvc under valve cover harness for any possible breaks or shorts. As this could be the cause to your inconsistant miss and rough running engine as well.
