Pulled the heads...bad news!
Pulled the heads on my '98 Ranger 4.0, took us about 4 hours to get it all tore down. Found what I didn't want to see, the head is cracked between in the intake and exhaust valve on #4 cylinder. So, now I'm looking for new heads. Anyone have recommendations on a decent company with good prices?? Hoping to have a new set by next weekend so I can get my truck running again.

There was a post in the last few days I saw. Something about heads with thicker castings?
If your not looking for more than stock power.. I'd just get a set of standard re-man heads.
Personally.. I could not let a opportunity like this pass me by! I'd get a set of ported heads w/oversize SS valves. A set of MLS gaskets. Then bolt them down with ARP fasteners. Even on a stock cam you'll notice the power increase. Add a cam speced to your type of driving and you'll really notice it.

Don't buy used heads for "98 - mid "00 4.0. They ALL will eventually crack if they are stock Ford 4.0 for these years, as they had "porous castings" from what the Ford dealer mechanics as well as others here have told me also. They even admit they should have had a recall on them, but since they usually don't fail until they get around 60,000 + miles on them most people don't realize they had a manufacturing problem with them. Even Ford won't sell you the same heads if you buy new from them, they are what they call "redesigned". I got new heads for mine from Clearwater Cylinderhead in Florida, they had a 3 year unlimited mileage warranty, I'm sure there are other quality aftermarket companies, we have always used these people because of the warranty and had no problems with anything we've gotten from them.

I would never buy a used head for this motor. You would end up doing the same repair later down the line, it would just be a matter of when. I got mine for my 99 at www.idealcylinderhead.com it took them a while to get it to me but they were cheap, and they were different than the factory design. I have read a lot of really good things about http://www.alabamacylinderhead.com/ too. I remember researching the swap on several forums, and IIRC there were a lot of members who got theres from them. I would also replace both while you have it apart.

I would also very strongly recommend replacing the push rods and lifters while you have yours apart. They wear very fast on these motors and start to chatter quite a bit. I'm going to have to pull mine apart because I was lazy when I replaced the heads. You can find those kits on ebay for cheap.
