Anything else I should do when swapping intake/carb?
finaly got my carb & intake in for my '86 F250 460. I planned on the usual gaskets, thermostat, dist. gasket, PCV valve and removing any emissions left overs. Anything else I should tackle? I'll probably do a full tune up with distributor/plugs/wires. Gas filter, air filter & housing, misc wire removal.... I'm hoping most of the vacuum lines will be sorrted proper. the P.O. removed the smog pump and put a hillbilly bracket back in. I'd like to get a 70's alternator mount to put back in. Something other than a big slab of steel.
Any preference on a 160 thermostat vs 180 deg? I don't run it that hard and live in the Seattle area.<!-- / message -->

160 is too cold. You need to get the engine oil hot so it will burn off the bad stuff out of it.
With all that stuff you listed, I would leave some of it till later. I would do this in stages, one thing at a time. I would leave the wires alone, the dist alone, just swap the intake and carb, and get rid of vacuum lines that do not have a home. You will have your hands full with just the carb intake swap, and getting that sorted out.
After that, you can pull some wires, and see what happens. Then work on the dist/plug wires, take baby steps.

I agree with Franklin. It makes it easier to take it in steps. If you do it all at once, then it can make it harder to diagnose a no start or driveability problem, since you have just messed with your air, fuel, and spark. Do you still have the EGR? From what I understand, you should still leave that, as the rest of the engine is designed for it.

Yeah, the EGR is there. I'm getting it back more to 70's type configuration, less gizmos. It's not a daily driver, it sits most the time, but the PO tried to 'modify' the carb and broke some alum. The intake is also stripped in 2 places. The intake I got is a performer 460 and someone used a sandblaster on the machined surfaces. Its just slightly pitted, I'd like to seal them true flat with something like Jb weld, then use a flat bar to sand that true.
You're probably rightm i should do the fiddling in steps.

I think I'd skip the JB weld if it's just a little rough, maybe some wet/dry sandpaper with the flat bar or maybe the gaskets will seal as it is. Wonder what a machine shop would charge to mill them for you?
