Just finished my 292 and I don't have a clue what kind of plugs to use.  It is a 292 bored to +.040 with a B intake and and headers and a little bigger cam.  What are the new part numbers for Y Block plugs?

Tom, here is a link to spark plug recommendations on John's site. I used it after installing a mild cam and milled G heads on my 312. Ended up using  RF-11C Champions and have been happy so far.
