Making a few tweaks to a set of Dart 18 Degree Big Chief heads. Intake got some changes at the shortside radius, and exhaust port got some more bias and cleaned up a bit. Results fell right around where they should and have in the past. The same changes on a cast single 4 barrel 632 was 70 hp in a A-B dyno test a few years ago. We will see how a 706 reacts to the same treatment.

Switched up valve job to 50 degree seat angle and a quick blend in a attempt to fix a poor choice of angles in the past.
