Recommended spark plugs for H.O. ZZ502 Deluxe.

[sdkar]

Hey guys,

I installed a GM ZZ502 HO crate engine in my 69 Camaro.  It has a Holley 850, and sadly, fouls out spark plugs quickly.  The 502 came with the AC Delco rapidfire #4.  Is there another spark plug that will fit and possibly work a little better and not be so prone to fouling?  I was recommended the Bosch 7956, as it is supposed to be a hotter plug and will help burn off the oil and help keep from fouling.  Any other suggestions?

Thanks,

Steve
