okay, i got one more question. I have the head off and all the headbolts i took out are clean except both the second to last ones from the front of the motor are covered in oil. What does this mean? Is it bad?

Nah, just make sure you clean the head andblock surface and that theres no oil or coolant in the bolt holes.
