I’ve started trying to access the head gasket and I don’t know the order etc, to do it in but would like the instructions for a advise/mechanic. Please and thank you. Picture shows how far I’ve gotten and I’m probably completely out of order.

Hi and thanks for using 2CarPros.

First, I am going to provide the directions for removing and replacing the cylinder head. I see you got the valve cover off, but I am going to provide the directions in order from start to finish. The directions include valve removal. I didn't know if you needed that or not, so I'm adding them. The attached pictures correlate with these directions. After these directions, you will need the directions for installing the timing belt. That must be done correctly.
