I have the same setup and have Dougs, other than the need to modify the Z-bar they fit great. I have a cast Iron bell housing and there are two "nubs" on both sides that hit the headers. They fit but contact the headers, so they need trimmed off. If you motor is not in yet I suggest installing it all on the k-frame and bringing up from the bottom. You'll need the 90deg oil filter adapter and/or a short filter too.
