touch control cylinder head

I have been working on the hydraulics on my super c now for a week. I overhauled the hyd pump, am still having issues so I figure it is the relief and pressure valves inside the control manifold. I drained the hyd tank, took out 14 bolts from the head, then took out the set screw at the bottom. I cannot get the head off, is it doweled in place, or is there a certain way it comes off? .

Anyone done this before?
 
Probably the last guy glued it on really well, so it wouldn't leak. If you have all the bolts out, you just have to abuse it until it comes off. Try a soft hammer against the sides of it in all directions. Try some heat, heat gun not a torch, unless you are very careful. Last resort, a thin wedge at each corner, then progressively thicker ones when it starts to move. You will probably wind up splitting the gasket, with part of it on the head, and the rest still stuck to the block. Try to keep all the metal damage on the outside half inch of the surfaces, and smooth it up before reassembly.
 
I have removed a head from a C and a Super A, they did not want to come off. Get a rigid paint scraper and drive it carefully between the head and block. Do that in several places and do not drive it all the way in to begin with. Also a lot of info in the archives on this site, including pictures of the internals. You need a kit from CaseIH, which consists mostly of gaskets and orings $120+, but I wouldn't try to fix it with out the kit.
 
The only thing you mentioned I hadn't tried was the heat. I did abuse it, but I'm always overly concerned about breaking something. When I make mistakes it seems like they are expensive.
 
You can use the scraper I mentioned without abusing the head or block. You can use a small screwdriver to CAREFULLY pry it up after you have moved it slightly with the scraper. I have done it twice. You do not need heat, you just need patience. I had to have a cylinder head milled once because some idiot in a hurry jammed a screw driver between the head and block.
