not sure if theres much more of a gain, but i got em on my car. yt 1.95's oddly enough i got em from the same guy who i posted up there.

they do need a washer under the pedestal and different push rods.

when i first put them on i was all stock still. (im still pretty stock lol) they cleared up 5* kr right off the bat, no tuning. i had 8*.
