If you're looking for an almost new 16 valve head, I know where you can find one. I recently purchased a Volvo on eBay from a seller who runs a small chairty car lot in Chicago. Of the 50 or so cars that he had, at least +5 of them were Volvos, and several of them were in good condition. While I was picking up my car, I took a quick look at some of the other Volvos on site (mostly 740s and 760s, turbos, etc). One of the cars was a 740 ('89 I believe) that looked like it had a brand new 16 valve head installed just before it arrived at the lot (aluminum head was VERY shiny and showed almost no dust or dirt on the finish, very recently replaced). At the time, it was not in running condition and I was unable to see if a simple fix or two would get it started. It may need a few relays replaced or major work, I'm not sure. I would suspect that the new 16-valve head is probably ok since the timing belt is typically replaced along with the head. If you are interested in buying a car, or just the head, please feel free to give him a call. Dan's phone number is listed in the auction, he was very helpful and accomodating throughout the entire process of buying the car:

If you're interested in converting your stock clutch fan to a GM electric fan, here's a post that covers the wiring, relays, and related info.

However, I would strongly advise mounting the GM fan in front of the radiator as a 'pusher' fan and keeping your stock clutch fan in place since it provides unsurpassed reliability and security against overheating. There isn't much of a horsepower increase in removing the clutch fan, and it's good protection against a warped head. (Warped heads are a typical occurance of overheating a Volvo engine since the aluminum head expands at a different rate than the Iron block).
Lastly, I forgot to include some information in the Electric fan post. You will want to install a temperature switch in the Volvo radiator to trigger the relay to activate the fan, but this is a discussion all it's own. Your radiator should have a sensor port on an upper corner pointing backwards towards the engine or out to the side. You can remove the little plug and install a thermal switch here. I think that you can buy one of these from Autozone for less than $20, and the part number is SW1802 (made by WELLS). I could be wrong, but I'm pretty sure that this is the thermal switch used in the 240s with stock front mounted 'pusher' fans (typically found on 240s from the 1990s). You may want to do some research on this before buying any parts, I'm not sure what temperature the switch closes at. I would assume that it's a 2 conductor switch, and you tie one line to the relay signal wire and the other to ground. -but again, check and make sure.
God bless,
Fitz Fitzgerald.
