Pick a wedge head with combustion chamber similar to your early mopar head
ie flat with no raised area away from the plug like the 902-906-452 etc
Figure out what cc choices you have your heads are supposed to be 74 but more likely 80
Edlebrock has two choices
then you want the piston part that is under the head at 0 deck
depending on how much compression you want you will most likely end up with a D DISH or a Step Dish on the spark plug side
then pick your pistons to give you the Mechanical (static) compression ratio you are looking for
then pick an intake closed point to give you the dynamic compression you are looking for
have a good idea what rpm range you want your torque at
if you pick a cam with the intake closed point to give best dynamic compression - not to much = detonation too little you loose torque
you can go larger on the lobe duration the more you squeeze the lobe centers together- which gives worse idle
if you start making the cam longer and increasing the LOBE closed you loose low end but your can gain on the top end with a bigger lobe but now you are into the looser converter lower gears merrygo round
there are those who can help on the DCA trial and error selection process- it's all trade offs
start with the KB pistons and play with the cc's and the heads
once you price it out you may find a stroker kit is not much more money than building your own
