NGK plugs for AFR heads and 250 shot?
Hi. I am currently running auto-lite plugs but I would like to run NGK's.AFR says you have to run "gasket type" with these heads(190s),which I am with the auto-lites.The plugs I would like to run are the TR8's or possibly TR6's,but they are "tappered seat".Does anyone know the part# of a NGK plug (14mmx3/4" gasket style) that is 2 steps colder than stock heat range? Thanks in advance

On my 210s, i started off with the autolite plugs as suggested. They got fouled up because of some internal issues, replaced them with tr6 and havent had any issues. The reach of that NGK is slightly less, but i havent noticed any ill effects of the seat type.
