Plug for Steel heads on spray

A friend of mine wants to spray his 429. It has the big plugs (currently Autolite 45s). What would be a good plug for the jug? Would rather have an NGK but Autolite would be ok.
Thanks and cool site

Autolite 124's, Ive used them for years and sprayed a TON at them. Theyre cheap and readily available at your local autoparts store.

Are these fairly easy to read on spray? How much is a ton?

Theyre as easy to read as any other Autolite plug. NAPA and Carquest in my area have always had them in stock for 1.89 each I usually buy 3 sets at a time, but I buy them pretty regular so that may be why the places I usually get them always seem to have them in stock. Oh and BTW Ive sprayed 45's also(not quite as aggressive) and never had any issues, just remember they are a projected tip and have less room for error. A ton is 345 or so to me on a single plate, opinions may vary though.

The first mom and pop store I stopped at today had them. I guess I will get the guy to buy a couple sets just incase. Thanks.

JMO. But I've found the NGK's to be a little easier to read than the Autolite's. Others may find it the opposite, but like I said, just my opinion.
