I answer spark plug questions all the time. It's a real benefit having the vendor catalogs and the Summit website handy!I didn't know Vortec plug depth was longer than TBI, I was under the impression the manufacturers made them longer reach so they wouldn't strip out in aluminum heads. I guess that stands to reason since they're still taper seat and not flat gasket - learn something new every day
