Call a Napa or O'rielys etc find someone who has some basic knowledge and ask them for the correct plug fo a late sixties ss 396 Chevelle (good start point) 396/427 heads if memory serves use a long reach 14mm gasketed plugs Vs most other BBC's which use the short peanut plus Casting numbers on the heads would help Tom
