    If an engine has a crankshaft port timing that's open for 180 degrees (for instance opens at 40 degrees ABDC and closes at 40 ATDC) then it'll have the same timing if the front housing is turned so...

    I'm not a metallurgist but if it's for a ringed piston then I'd say any decent alloy would do but if it's for an ABC type liner then you have to be careful to select an alloy with the right silicon...
