I have been so tied up between Work, Fixing up my House and Playing around with some Metros that I haven't had alot of time to spend here (or drive my XFi). Thought I would let you know that I have a few Metros for sale on Craigslist.org
PS - do you happen to know if the cam is a straightforward swap? Is the cam gear different as well? Just a matter of setting everything to TDC and aligning the gear marks to the plane of the top of the head?
