You have a better chance of being run over by a train w/o ever crossing a train track than having a head gasket leak.

It's the valve covers. Yes it's rpetty easy. 87inch lbs for the torque on the 3/8" valve cover bolts. 10mm will round them out. Yeah..I'm a little over the top huh?

13mm ratcheting wrench helps to take off those pesking brackets that are in your way ..
