Sealing up 340

Bores that are out of round will tend to have the ring gaps all lined up on the side that out the furthest.

as long as the valve notches r correct for the valves...its not that big of a deal and can actually free up torque by lightening the side/skirt load...though they be a lil noiser..its ok and an old trick for power-mentioned by smokey yunick in his books.
However one side being different says that maybe a retarded uncle brother named fred bob must have put it together..lol
