A friend of mine bought a rebuilt V8 that needed some valve adjustment and when the intake was removed we noticed some differences immediately. There appears to be a strengthening rib cast into the block between the valves in the lifter gallery. In addition there is an third undrilled boss beside oil pressure bosses on the rear of the engine. The numbers cast into the integral bell housing are K25611L and then there's a B6 to the right of that. He doesn't want to pull the heads to see if it has factory relief...Does this sound like a military block?
