Ok guys I had a min to run outside and I pulled one head off. And I have found a problem alot bigger than cam selection. I'm not sure how this happened because the engine has been inside covered in a tarp for the last seven years before that it was driven daily. But anyway two of the four cylinders had moisture in them and are rusted/pitted. I snapped a few pics it looked like it was covered mud it's not its greasy muck where I used a greasy rag to wipe off the piston tops. Kind of a mute point at this point but measured the pistons they where right at .064 in the whole without the gasket and the gasket miced at .043. Must be aftermarket? Here are some quick pics I took. I had to run in the mosquitos where carrying me off.
