Anyone know the stem height on 340 j heads on intake and exhaust should be or what they were on stock j heads. And can u use roller rockers

The rocker arm ratio doesn't change with roller rockers. Sure you can.

IIRC 4.981... rollers are OK but talk to B3racingengines.com about the valve train correction kits they sell. Worth the $$$ IMHO.

What Krooser says
he does not spend tight dollars unnecessarily
Jones cam- B3 shaft relocation kit- get the valve motion from the lobe to the valve the way Mike designed it
BTW nice score on those W2 rockers

I got some old crane gold rollers on my J heads..nice upgrade if you have a bit of a cam in it
