Local shop says I don't need to stud
My current setup - 08 6.4 - I have a 5" flow pro pdf/cat delete, egr delete with the elbow, H&S mini max, and an s&b intake. Advanced diesel, my local diesel shop (that's all they work on) says that I don't need to stud my heads even for a piece of mind. They are an H&S dealer and installer and are very mod friendly and experienced. He said in all their years of being in business working on all models and years of the big three that the 6.4 he talked very highly of for being a really strong base. They did my egr delete and knows that I'm making my truck really reliable. I e been talking to him about studding my heads for piece of mind and preventative maintenance. He had me come into his shop about a month or two ago to look at a 6.4 that is the ONLY one that they've worked on that had a leaky head gasket. Not even blown. He was studding it at the time. The guy towed heavy farm equipment every day and did truck pulls etc. he said that that guy pushed his truck and if there was a weak link that guy would find it.
They said they stud 6.0s all day long which I knew of and said the 6.4s heads are 8lbs heavier of material than 6.0s and showed me the stud size differences between the two. Which I knew the 6.4 was a little more stout. Anyways he said he could do the studding if I wanted but after doing the deletes I could run on 300hd and not have an issue with the hg. He is that confident in the motor, as long as I'm not driving like a complete idiot at every stop light.
However, studding would still make me confident as for bullitproofing along with coolant filter and fuel/water seperator.... What do you guys think? He said he could stud it for just over 1k
