I'm finally re-starting a project I started a few years ago and need to ask a couple of questions: I have what I think to be a JDM A12 shortblock (front-mounted dizzy, etc.) The ID number on the block is A12 033455.

Am I correct in assuming that I should use ARP's 202-4202 head studs?
(pre-74 A12????)

Next, which head torque specs should I use? "Lighter?" Medium? "Heavier?"

Last,any recommendations about the choice of headgaskets?

Thanks Very Much,
Pete

All the early A12s look like that, including AUS, USA, South Africa. And JDM.

The torque spec depends on which head bolts you have. Use the lower unless you have the "13" bolts then use the medium

See ARP
