Direct Connection ( Mullen LA ) heads

Just so I’m clear on this....... you have documentation from “back in the day” showing the reworked Mullen’s heads flowed 83cfm@3”??


I have to believe that a set of ported X heads flowing in the 280 range would pass tech..... no?
Correct, My BAD! It's even listed as a T/A head (DOH :BangHead:). The ones indeed known for offset pushrods and rockers for port enlargement. The heads on this thread use a W2 rocker and have a more extreme pushrod relocation than the T/A head. According to the MP manual, the T/A offset rocker does not have as much offset as the W2. But, indeed, damned if that bench doesn't make me think of a mainframe computer the size of a wall mount bookcase that might have the computing power of a T.I. handheld scientific calculator....
Because of the TA head , I can run these like you noted !
