'86 Removing Emissions & Timing Chain Install

As the title suggests, I'm changing out the timing chain on my '86 carb'd 460 with a straight up set that's for the EFI motors.

While I'm ripping things apart, I took the liberty of tossing both smog pumps and related emissions crap. I have about 50 lbs of crap laying in my driveway now, all having to do with either A/C or emissions, neither of which I plan to reinstall.

One problem I'm having is I can't get the metal tubes out of the exhaust manifolds, they're stuck and no amount of PB blaster and wrenching will break them loose. Any easy solution short of replacing the manifolds?

I also have this hose which comes from the back of the engine (maybe the right exhaust manifold?) which I have no idea what it does, or what I should do with it. I'm not sure if it will leak exhaust (unlikely as it's a rubber hose) or what exactly this thing is going to do, now that the other end is cut off. Here it is pictured:

The only trouble I see myself having is putting back the evaporative emissions charcoal canister stuff; I assume I want to hook that junk back up so there's no fuel vapors in the engine bay? Most of the vacuum hoses were tied up together, or part of the big metal tube assembly, so I lost some of the hoses for EVAP in the process of removing the smog pump tubing. That will be a project for another day.

Last thing I'm stuck on is how in the world to get the crank pulley off? I got the bolt loose by putting the transmission in reverse and chalking the wheels + applying E-brake. That part was a piece of cake. But now I have about 4 V-belt pulleys and the harmonic balancer to get off. Can someone give me a step-by-step on how to remove these?

Thanks in advance for any help/info/suggestions/etc.

as to your balancer / puller issue unbolt the 4 small bolts that hold the pulley to the balancer, as for the balancer go to your nearest parts store that rents tools and ask for a harmonic balancer removal tool, they bolt in place of the pulley and use a forcing screw to remove the balancer just be sure not to bugger up your crank in the process. as for the smog stuff ive been told (wink wink) that you can simply crimp the ends of the tubing at the manifold if the fittings wont come off. and as for the rear of the head connections those also need pinched off or they will leak exhaust/ ingest dirt. be sure to use pre emissions tune up specs after the mods if you have performance issues.

How are you doing? I just finished up doing the same thing. New double roller using the 0 degrees keyway, emissions gone, EGR working, new distributor.

On the rear crossover can't you just plug it off where it used to go to the plate? What would it hurt to leave it on the heads?
