Follow the firing order (any motor)...look at the distributor cap, whichever one is at TDC, the one before is heading for the exhaust stroke (so lash the intake valve), the one in front is heading away from the intake stroke (so lash the exhaust valve).

FWIW, I've repeatedly found this gives a lash that is too loose on those "before and after" cylinders, so I just roll it over two cycles and do the cylinders in order, checking the lash on the before and after cylinders along the way.
