It's not a straight swap I'm afraid. You need to drill and tap the cylinder head for some of the mounting bolts (1 I think off the top of my head) and if it's the same as a 197 inlet the ports in the manifold are higher up. You need to do some serious porting to make it work. By the time you've done that the inlets on the head will be huge. There's ways and means of overcoming the issue, but in all honesty you may as well buy and fit an rs2 inlet manifold. It'll cost you the same for the rs2 or the modifications.
I've adapted a 197 inlet on to a 172 head so trust me, it's not worth the hassle.
