.15 to .21 head compatibility?
Stupid question, but is a big block head for a .15 the same size as a .21 head? I'm struggling with finding a head specifically for a big block .15, and I'm wondering if my options also include .21s, too.
As long as I'm at it, does anyone know of who would carry RB parts like a replacement head?
Nothing is always.
Everything is sometimes.
