I thought about KDD heads and went to the shop in Texas that imports them by the pallet from China and saw it all. Glad you guys had good luck with them but I’m not crazy about the idea of imported aluminum or iron heads. UCF were great to work with and I wanted to do it once and be done.

Yeah I get the whole imported from China dilemma and the possibility of failure, but for some reason, KDD must not experience any of this because I have never heard of ONE failure from his company's products.
I looked at Jared's track record and endorsement from Charlie over at KC Turbo and decided it could still be a gamble. After talking to Jared personally on the phone, I knew the choice was clear.....at least for me.

From what he has said, Jared goes through the cores and rejects those he doesn't find acceptable. But I think he also said he has a deal with the supplier, which may mean the bad cores go back into circulation elsewhere.
If I was going the O-Ring route, KDD would be where I'd go.

If so, wherever Mark. These days, maybe to Nav.
The motor is about 10 years out from the E series applications, and that's normally the time limit for parts inventory from the original supplier.

Now I have a few more questions.
1 would a leaky head gasket cause the issues I had while I was towing a couple weeks ago. I had fine temps for an hour or so, then the temps were all over the place.
2 I guessing i have a small right now, since I don't have the classic symptoms. No puking, no coolant, no real overheating.
3 is there any thing else I should look at or just get ready to do the gaskets?
Thanks

I'm in the same boat. I think I will be going with new KDD O-ring heads as well. My overheating problem started slowly getting worse. This last trip my truck finally got the hottest it's ever gotten, up to 236 ECT. I'm putting together a parts list and hope to get started soon but it's still hitting triple digits here in Central CA and it's hot in the garage.

Ok so now I need to do the head gaskets so I am developing my parts list and it is getting long.
Heads KDD
ARP head studs
Head gaskets Felpro
Valve cover gaskets Felpro
rocker box gasket Felpro
Push rods OEM
EGR gasket KIT OEM
Thermostat OEM
Glow plugs OEM
Injector seal kit OEM
Stand Pipes and Dummy Plugs OEM
Exhaust Gasket Felpro or OEM
Exhaust bolts and spacers OEM
Radiator Cap OEM
EC-1 Coolant
new oil and filter
I just replaced the oil cooler recently and my deltas are good, so I plan on leaving it in place.
I am trying to decide about one of those coolant return kits.
Is there any thing else I should consider or add to my list?

If you have over 100k miles on it I would replace the lifters you have access to. If I ever had to do heads on another of these motors, I pull it so I could replace all the lifters.
I’d change my mind if a few people with 100k plus miles destructively inspected the lifters and I saw the needles were all excellent.
