Taking another look at the cutaway Boss 302 head, this time on the intake-port side, reveals the general streamlining and gorgeous blend between port, valve seat, and combustion chamber. It’s tough to remember this is a production Ford cylinder head. Another CNC advantage is it allows a multi-angle valve seat. Ford calls it a five-angle valve job, but there’s actually a sixth angle hiding in there. It’s just another step toward the holy grail of fully radiused valve seats. Intake port volume remains at 193cc, same as the Coyote, to avoid velocity losses at low rpm. It’s going to be interesting to see how racers and hot rodders can improve these heads.
