OK, first stupid question of the year.
I've got a 50 hp case and I'm putting dual port heads on it, 85mm cylinders. I forgot that the 2 center case studs needed to be shorter for the dual port heads. OK, so back to the shop, 4 new studs, remove the heads and put the new studs in and they are too short. Just to see how it would work out, I backed out the ones on one side a few threads, just enough for the washer and the nut to make full contact and it'll hold and torque OK but I just don't like it.
So, suggestions? Besides the obvious, I know I'm going back for different studs but thats a few days off now. Work is getting in the way of my toys.
