383 power upgrade help

In the mid/late 80’s I re-ringed several BBM’s that turned out pretty well.
Same formula for all of them.
Get the block & crank hot tanked
Dingleberry hone bores
Polish crank
New cam bearings and expansion plugs
Heads reconned(only what they needed, generally a valve job, new ex guides, resurfaced)
New hp springs
Some sort of typical hot street cam
Aftermarket intake
New carb
Headers

All of the ones I did like that I considered successful and the owners ran the heck outta them for years.

Of course……the cores are all close to 40 years older now.
