i ordered some intake gaskets from macs auto parts for replacing my intake ,i havent taken the old intake off yet and havent received the replacement intake so i cant check the holes ,i opened the package of gaskets and held them together they are the same size and everything ,but the holes are offset on the gaskets(not in the same spot as each other)..Are they supposed to be like this ????ive only replaced a intake on a y-block once and that was a few years ago...tim
