Heads up - Caution
B faces the intake (valley)

Hi plc guru, personally I would put the "B" side to the exhaust here, towards the outer side of the block. The valve notches go towards the intake, the lifter side. That's the way it's done. Unless I'm missing something here?
(Add) The chamfer and bearing tang location's you have correct, tang's to the pan rails, large chamfer's to the sides of the throws, away from each other.
Thanks, Gary in N.Y.
P.S. Not sure what Mike was thinking here. I know he knows which way they go!
