Dunno why you are pulling the heads you did not say... Back in the 80's I had one with low compression I yanked the heads it needed head work BAD $$$$ a few weeks later it showed back up at my door guess WHUT it had low compression lower than before WTF... After a lot of checking I pulled the timing cover the dots on the crank/cam gear were aligned WTF... What the ell could be wrong with this thang,,, The fix the key way on the crank gear had wallered out it was out of time...
Pull the intake make sure the bolt holes that hold the intake to the heads are blind are it will suck the oil out of it... When you go back get your pocket book out and buy a tube of the right stuff from NAPA and run a good bead of that instead of the intake end seals that come in the gasket set life will be good...
Next if you send the heads out they will resurface them lay the intake on the heads with un-sealed gasket and make sure all the bolts start nice and EZ if not the intake will need to be resurfaced... Are if you put the gasket on and find you have to fight a few bolts STOP and have .025 to .030 shaved off the intake gasket surface..
I would locate exhaust manifold gaskets like the original "ALL STEEL" Those zaust manifold are always fun LOL... If the heads coming off and they put up a fight I go ahead and let them snap off set the head in a mill and drill them out... You can spend quite a few hours trying to save them and still lose the battle... Snap'em off a good machine shop will have no problem drilling them out...
BTW I seal the intake gasket with Permatex Aviation Form a gasket :) Total timing without looking for the spec 28/32 deg total if you do not understand total timing it would be a good time to look it up...

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
