When removing the head, CLEAN OUT AND DRY EACH HEADBOLT FIRST! Also, go to snap on, and buy the XZN tool set. It's about $140 it's worth it. The bolt heads are shallow, and if you are even slightly off center, you need to drill out and or grind off your mistake...
Find a diagram of the HEADBOLT tightening sequence, and remove in the opposite order.

You should take a hinge handle and a speed wrench with you for bolt removal, also bring a magnetic pan for bolts, and a magnet-on-a-stick and good flashlights... Dropping things is annoying!
