How big of a job to do valve guides in 66 429?  I'm replacing intake anyway to deal with exhaust leak and while it's off, what else?

After oil change last week, on start up after it sits all night I'm seeing blue smoke for a few seconds, but only on start up, which tells me valve guides.  Didn't really notice anything until after oil change so it looks like someone might well have added some secret sauce additive to quell it until sold. 

Since heads have to come off, I guess a valve job would be prudent.  Oh hell, why not find a rebuilt 472 to drop in?  Right?

I'm trying to figure out what order to do things so I don't end up doing them twice. 

It never ends !!

Your valve guides are probably fine.  Blue smoke on startup would be valve stem seals replaceable with the heads on the car.

Right.  Should have said seals.  Heads have to come off to do this, correct?

No, not to replace the seals. There's a tool you can get to use an air hose in the spark plug hole that allows you to remove the valve springs without dropping a valve into the cylinder. The air pressure holds your valves closed.
My compression tester has a coupler on it that matches my air hose fitting, so that's what I use to do this with.

THANK YOU !!!!

It's a new car Chebbie dealer close by who is remarkably talented when it come to old cars.   

The deal is that I make sure that I have parts in hand so I don't tie one their few lifts or stalls up waiting for parts.  So far, I've been 100% ….. so keeps them happy and keep the neighbors in this HOA out of it so they don't burn me at the stake.  Not the cheapest way to do things, but if it's going to be a little noisy, I pretty much have to.
