Spark plug for 882 headed 355?

[18mmod]

What is the best spark plug for the 882 heads on a flat top 355? I have previously used NGK in 462 heads with good results. Which is the right NGK plug or what other brand is better? Thanks

Call a plug manufacturer like ngk and give them your specs! Ci really isn't to crucial! Pistons, cr, valve lift etc make all the difference! Remember many plugs will fit and run but there are different shank lengths and tip yo get your fire in the whole deeper without destruction! Most are running an 8 heat range

call ngk at 877-473-6767 and they will get u very very close great people to work with!
