318 Build.. Zero Deck or Stock Deck Clearance?

Ok
if we are thinking of a cam in the 256-260 range (would not ever use old comp 260h in 2018 no lift)
I'd build it with 302 heads and 9:1 are you going to build the heads you can think of larger intakes and a multi angle valve job and hand blend
302 are closed chamber wedge with heart shaped chamber and are called swirl heads- all SBM mopar have swirl but evidently these have more
600 AVS carb is about right
I posted a whole list of short cams in the 340 cam thread which we can look at with different LCA's check it out
340 cam specs? see post 27 and 37& 38
the 256 comp is there and several others listed by duration but nothing from Bullet or Engle or Crower but you can get the idea
post 27 reads from shortest on the bottom
Aj what DCR would he have with a IC of 54-56 @.006? about right on the DCL? too much or could he use more with the fuel gotcha?
what pistons to use for -.010 to +.010 deck (for .028 Mr gasket or .48 Fel Pro) gives .038 quench but .028 is also OK
If not rebuilding 302 check out the Engine quest heads any other suggestions? CCs?
If we have to drop to 8.5 then forget the 260 and pick a higher action 256 or would he spring for a custom grind
we can get to the proper DCR either way
any idea what gears are in the cuda?
the 302's end up around 63 cc unless relieved around the valves to say 68 if necessary
guys- give some help on the pistons
