Grey Motor Spark Plugs

Hi all,
What spark plugs are people using these days in a stock 138 Grey motor?
Cheers

Graham,

. . . the ones I was using twenty years ago.  Pull them out, clean them, gap them, put them back in.

Sorry, couldn't resist.

Champion J-12Y, NGK BP6S, Bosch W8FC (?).  The plugs for a grey motor are the same as for small-block Chev V8s, but a couple of ranges hotter.
