Teach, I gotta say I'm proud of you on this one. Good job on diving in there and doing this  Thanks David! I am actually surprised that I got half of it done today, I did run into a few issues and I had to call someone to assist me with removing the manifold bolts on the bottom side. |

You're always better off calling for help on something instead of messing something up. And hurry up and post a build thread on this thing man!!!

Another question
Since I'm reusing the pushrods and moving the lifters over from my old head. Do these have to be set or how are they done?

if memory serves me correct, I think on my 4.2 the rocker arms were on a rail and just bolted in place. Like a pre-adjusted deal.

Oh......
ASSEMBLY LUBE ON THE BOTTOM OF THE LIFTERS AND BOTH TIPS OF THE PUSH RODS.
Once you drop the lifters in just make sure the ends of the push rods seat properly in the top of the lifter. They typically center themselves up.

Idk why I said lifters lol
I meant rocker arms, I only changed the head and gaskets. However I will be buying new head bolts just to be safe. The exhaust manifold gasket looked like it had been replaced

Be sure to put oil on the threads of the new headbolts when installing them and be sure to change your oil before you start it in case coolant got into the pan during head removal. I hope you have a good torque wrench for this.

Thanks lol I borrowed a torque wrench from a friend However I can not figure out how to torque the rocker arms, everywhere I read keeps saying put it top dead center |

With the head on, put something like a VERY LONG straw or something non metallic that's very long and put it in the #1 cylinder and then rotate the crankshaft SLOWLY until whatever is sticking out of the cylinder stops moving up wards and that will put you in the ball park of TDC
hope that makes sense

The rocker arms are the only thing left to do to head |

The rocker arms are the only thing left to do to head Top dead center means the piston on the #1 cylinder is at it's highest point in the rotation.. That's all.. sticking something in the head to make sure it's at it's highest point is how to check it.. |
