Which heads are those? Any pics?
EDIT: scratch that.....EJ20K heads you measured....
Also...I was talking with one of the guys who had a STi Ver7 head. He noted that they where the small ports. The intake ports where IDENTICAL to the USDM WRX heads as well as the USDM STi heads.
So this means that the small ports are the ones we got; USDM WRX/STi heads. 2 different castings for the NEW PHASE heads; MY00+ GD.
