The Ford Barn - View Single Post - Question for the guys running aluminum heads

I've seen a lot of heads, but never an early Edelbrock with 3/4" reach. My guess is that they take a 7/16 to 1/2" reach plug - but you'll have to measure the thread depth. Truth be told, I bet I could just look at the plug threads and I'd know what plug to run.
