craftsman chainsaw 20" 54cc 3.3 ci cylinder removal

There are no bolts on the bottom of the saw. Looks like removal of cylinder is thru four screws on the base of the cylinder. Impossible to get to. body on this thing is all one piece nothing comes off. The screws are inset under the fins on the cylinder. I ground down three allen wrenches and managed to get three almost out. Special tool? The fourth is on the clutch side closest to the handle and I don't have enough room to get make the wrench work. How in the world do I get these screws out and the cylinder off? In case your interested I'm trying to change the rings out. The cylinder and piston are not good but I can't find replacements for the piston. I would like to clean them up as best as I can and at least replace the ring. Also I keep hearing that you can swap the top end out for something else that might be an option but have not been able to find a thing about it. I'm at a dead stop. Help! model is 358351202

Most top ends are like what you have. Many have torx screws holding the cylinder
to the block. Sometimes allan head bolts.

They make long, about 6", shank tools such as this:
