If I could get 420 HP out of a rebuild, I would be happy.
Any thoughts..

The value of the numbers matching motor is really only there in a restoration. I think you've gone beyond that with your car. If you are really hammering it then you risk destroying your #s matching parts so if the #s thing is really important you should think about that. I like the old school carbed stuff so I feel you there.
Since the block is specific to your car with Vin# (I think but I'm not a Chevy guy) it isn't worth as much to somebody else as the heads.
The heads are holding you back compared to a modern set of AL aftermarket heads.
So my logic is stroke your block and top it with a good set of AL heads. I like AFR but there may be better choices for a Chevy. Run a mild solid roller spec'd to the flow of the heads you choose along with a good intake that matches the power curve you are looking for. RPM air gap comes to mind but you Chevy guys may have another preference. I'm assuming you already have a good exhaust and ignition so along with that you should easily get into the 550hp range.
71 LT heads are iron right? So the AL heads should also loose you some weight over the nose of the car. That can't hurt.
