Finally got a 2013 3.6L head on the flowbench (SF-1020)
I only had time to get the Intake done but WOW! The Stock 3.6L head is a beast!
Intake port flow maxed out OVER 300cfm at .444". At stock intake lift of .405-.417", it's still close at ~296cfm.
Suffice to say, it kicks the crap of most any SB head.
