Manifold Hitting the Block

Thanks everyone -- especially Professor Fate -- for the input. I'm guessing that as you said, I have a '73+ head that has those extended ports. If the shop grinds the manifold and ends up ruining it or not being able to make it fit, I'm trying to prioritize my next moves.

1) Obtain a 73+ manifold. Would I have problems with clearing my 72 car's power steering box? Any other considerations?

2) Similar manifold with a fatter gasket -- does anybody have any gasket suggestions?

3) Similar manifold with a spacer (Header Flange). Seems like this would move the manifold out for clearance, but the ones I see do not look like they would cover the extended exhaust port surface on the 73+ head. Would this be a problem?

I say it all the time, but this forum is fantastic. Thanks all for paying attention to me and my car!
