Very common 24VP issue, good luck find another head without cracks. Lots of choices, to bad nothing cheap. I would buy new. Down the road spray water/methanol, it seems to slow down the cracking process. Probably search the internet and a cheap skate fresh head.
Another option is to find a 12V engine and just sell the 24VP engine. Tons of 24VP run around with cracked heads.
For my 6.7L project, I'm running the hamilton head and going with larger valves. Intake plenum is going to be removed. I also plan on running R&R rods, and a mains gridle. I just got my 13mm p7100 done up. Schieds sells a CR P7100 gearbox housing. It should look like any other 12V once I'm done, nothing special.
Might even throw a old banged up 215HP 12V valve cover shield on the engine, just for laughs.

I'm sure shipping would kill the deal on something like that heavy sucker... I'll keep searching.

I also came across some references to an IAT fooler to solve the cold weather timing shift that seems to be common with these trucks. You simply bypass the IAT with a 2.2k resistor.
Long story made short---my truck has NEVER run better in it's whole life!!!
Glad I didn't give up on it!

glad all worked out for you... I am also thinking about the ECM. Dont know what else to do. Dont want to just throw money at it... I figured by now it would get worse if something was failing but seems to be the same. I did clean all grounds, double check the Timbos APPS, unplug the comp and put a Raptor 100 lift pump on but same ol same ol. I was wanting a smarty anyway this sounds like a good reason to buy one

Well, I think I found it.... I didn't think it would be relevant because I unplugged the wire tap when I pulled the edge but, I took off the tap and soldered the connection this morning and now she runs like a swiss watch... Only think I can think of is maybe it was a combination of bad grounds and that connection. Thanks for the help guys hope this helps someone else down the road.
