If you do use longer crankshaft bolts make sure they aren't too long or you'll lock up the engine by bottoming out on the bearing cap.
I was referring to the GM performance parts spacer. This one goes after the flexplate, between the plate and the converter. This style requires bolts which are 0.400" longer.
