Last night I did the 171/174 overhaul. I bought the kit from 1A Auto.com. Anyway, in addition to the valve cover and gasket, isolator bolts, 6 port gaskets and plenum gasket there were 2 other gaskets which I didn't use or even see any reference for. I'm assuming that these are for some other installation, year,... One looks like a figure 8, the other as well like an 8 but with one circle much larger than the other. Here is the kit.http://www.1aauto.com/1A/ValveCover/Ford/Windstar/1AEVC00013/605003

Did I miss something?

welp, answering my own questions I've realized that these 2 gaskets are the throttle body gasket and the idle speed control gasket. Sooo, I didn't replace them. Do they commonly need replacement or is this a "next time I've got nothing to do" sort of thing?

Hi
The Ford kit came with those too. I would put it in the next time category. Of course the IAC gasket is easy to get to so why not? The throttle body is a bit more of a job, so maybe better if you have the plenum off again sometime.
