Head wise it greatly depends on if your buying a set of rebuilt iron heads ready to slap on, of if you will need to send them out for work before you bolt them on, and even initially what the shipping cost would be to just get them in your hands which is not cheap!
You very well might find that you could come within 300 bucks of just buying a new aftermarket D port head when you run the numbers.
Iron head wise my first pick would be a set of -4 or 4H heads from the 4X casting line of heads, or the 5 serise of heads with screw in studs, or a 6X casting, and all of these like I posted should have the 4 stamping to provide the compression your looking for to get into the 9 to 1 range without having to mill them but for a .002" clean up.
Other iron head casting numbers you maybe able to turn up would be 1971 # 96, 1972 7K3, 7H1
This all assumes that the motor has not been built with dished Pistons of course!
