svo and front of prod block should be the same. belt drives with the idler are suspect imo because of the idler bearing, some use ceramic but still wouldn't do it myself. i use a jesel, more $, but simple and reliable. if the belt breaks while on the road another won't help, i think these engines are interference type. after i got my engine up and running i didn't mess with the cam adjustment, would probably only come into play if you were serious and on a dyno. make sure you have a good strong cam, there is a bit of belt tension till things become accustomed to their new home. i used one on an aluminum block and the expansion stretched the belt and ruined the front cam bearing.
