They are AFD 4V units, 235 cc intakes. Bought them in 2015.

The plan - not in stone yet - is to cut them .012 down to 62cc and leave .005 deck on the block. Still fussing over head gasket thickness.

Chris, my recommendation is to use Cometics MLS, superior gasket to fel pro hands down...

It'll be Cometic. Have a good friend locally that is a dealer.

Just curious, why the neck down on the collector? I noticed on the Patriot headers I have "it went from 3" to 2 1/2" there was a lot of head building there.

Custom merge collectors. Increases low end torque. Pretty common on dragster headers.

The neck down is like adding collector length . The "choke" adds bottom and mid range but doesn't hut high RPM.
