I just did a RCD EGR delete and oil cooler. Found that my HG are blown also so I am putting in ARP's with Black Onix gaskets. Anything else I should do or upgrade when the heads are off? I have a 4" turbo back, turbo is rebuilt, gauges and I have custom sct tunes. Any advice would be great. Also what should I do with the heads. If they wrped should I just replace or get them machined? I am in the Harrisburg, pa area and have not found much info on good machine shops in my area. I tow so I am looking for reliability towing 10k.

It would help to know something about your truck. Updated STC fitting, dummy plugs, HPOP reservoir screen, ELC coolant. If the heads can't be cleaned up with no more than an .008 resurface get new ones.

The truck is an 04 with 66k on it.. I upgraded the hpop screen when I did the oil cooler. I did flush the complete system and use ELV coolant. I did not know about the dummy plugs. What are they? I read in another thread about the updated sct fitting but was not sure where exactly that was located. Is updating the banjo bolts to the 6.4 worth doing for a stock injector system? I have a background in building engins but very little knowledge of a diesel. I did the delete myself and that was my first. I will be doing this myself so I wanted to get it all out at once.

They go in the heads and are o-ring sealed. The STC fitting is on the HPOP located in the rear of the engine valley under the turbo and connects the HPOP to the branch tube for the HPOP oil system to the injectors. The banjo bolts are an easy replacement at this time and will help make sure you have sufficient fuel flow to the rails. A cross over on the rear of the heads would be a good thing to do at this time also to keep from starving the rear cylinders for fuel.
