These heads were prepped and ported by Butler. With the Pontiac 1.6 rockers we just could not get a good contact pattern with any of the 3 brands we tried. Bolted on Lunati BBC 1.7 rocker arms and geometry was perfect. Caster1 is using the same setup. Motor runs excellent if you saw the video in my build thread
