My 'P' heads had no holes in the back, so going from what I've read on here - The tubes to the backs of the heads unscrew out of the heads, and I believe Ford makes a plug with which to plug the holes. The tube from the H-pipe can be crimped shut, or fitted with a piece of hi-temp hose (heater hose) with a plug in the end of it. Get all that tubing crap out of the pass-side of the engine compartment, and now you can actually see stuff, like your spark plugs! lol!
I removed the pump and all the hoses. Used a plug and JB Weld at exhaust tube near cats. To plug the hoses off of the heads, I cut the rubber as short as possible and then used a piece of round aluminum stock with a c-clamp to plug up exhaust coming from engine. Works great, with no leaks...but new heads that are going in will eliminate tubing.
