60447 is for the 396/325/350 HP combo's for SS only. Too bad thought I was getting some aluminum heads.

The 60547 heads on summitracing.com says the spark plug hole is moved closer to the combustion chamber by .150 and the NHRA rule book says it has to be in the same location. Not sure how it's an accepted product
