we are looking to gain 65/150 hp/tq

Fueling around

You must be pointing at the break off screws.
I usually get the one that holds the AFC (aneroid) to the pump by drilling it out slightly and driving a T-20 tip in the pilot. I use an impact driver to crack the thread lock. If that doesn't work a hammer & chisel will sometimes crack it loose.

Once the housing is off the truck you repeat the same on the rear cover.

Here is one of the better one stop guides
