There’s some stageVI reading in the archives and some of Dwayne’s work. His porting on mine aided me in getting into the 9 sec zone in my old Mirada and they were far from a “max wedge” port.... it was actually a pretty mild, but strong 498 build. Kind of boring with a 5800 shift point . One thing that really woke mine up was going from the 4150 M1/spacer combo to a M1 RB Stage VI 4500 intake.
