For those of you that have installed the EXP 119 , did you have to modify the CB-00032G and CB-00032B baffle seals? These seals go just above #1 and #3 cylinders. The cut out doesn't match the lug on top of the head and the rivet holes don't line up with the holes in the baffle. All other seals fit perfect. I'm wandering if this area is where we find a difference from the standard IO-390.
