i just did that to mine you have to buy a shorter belt and yes you have to plug the holes in the back of the heads all you have to do is take the tube that is running into them cut them off and turn them around so that the flat side is up against the head sealing it off i used some rtv sealent around the edges and there was no exhaust leaks.
