What else should I do if I take the intake manifold off
 

I am taking the intake manifold off. To do some PMD and fuel line work. While I have the manifold off I intend to clean the area and replace the lower intake gaskets.

Is their any thing else you would recommend I do while I have the manifold off?

Drill and tap and install a boost gauge fitting in the upper intake if not already done.
Do the EGT gauge at the same time.
