Anyone know what spark plugs I should buy - stock 351 Cleveland from a '72?

Basic stock Autolites plugs work just fine. Tell the parts monkeys at Autozone, PepBoys, Kragen, Napa, or wherever that you need plugs for a 71 Ford Mustang Mach 1 (or Boss 351) with a 351 4V. They'll set you up. But whatever you do, DO NOT buy Platinum plugs. Your Cleveland does not like Platinum.
Excellent Garth. Thanks for the advice, I probably would have bought platinum plugs "These are the best right? Yeah, get those."
I use NGK UR4 V-Power plugs and have been very happy with them.

I use the Autolite Racing (designation AR) plugs and am very happy with them.
I can't recall the specific number at present, memory bank seems to think AR32, but don't quote me until I can check - but it's mid December before I'm home again to do that.

FWIW, I think I put these into my Pantera the last time I changed the plugs, just to try something different. And they seem fine. I don't recall if there was a discernible difference to justify the price though.
