Down to lower intake manifold, anything that I should do while here?

[Exploring XLT]

Is there anything that I should check/do as I replace the lower intake manifold gasket?

You could use the opportunity to check the rockers and pushrods for wear.

How would I do that?

Sweet thanks, also, I have a max trim level reached left side, I have swapped injectors side to side, replaced 02 sensors, cleaned maf sensor, and replaced the coolant temp sensors, no change, searched for vacuum leaks, but could find none.

How big of an issue is this?
