Anytime you pull off any thing on the vehicle like a head, intake or exhaust manifold have it checked for warping and cracks. A machine shop can do this and they are pretty reasonable in price. I suspect that your head either is warped or cracked. They can do the check for you and if cracked you will need to replace it. If it is warped they can generally plane it back to specification.
