Treating a 6.4 like a 6.0

Lately I've seen more and more people doing head studs on a 6.4. My question is are you guys so wrapped up in the 6.0 issues that you think you need to do it on your 6.4?

Or are there a lot of people blowing head gaskets on the 6.4's? (I see a 6.4 head gasket blown thread 1% as often as the 6.0 thread...)

I don't think it's so much that they're wrapped up in 6.0 issues but more that they want to be safe. They want to know that they can make big power without thinking twice if their HG's will blow. It's not only 6.4 guys that do it too, if you go on the Cummins forums, there are a similar amount of guys with studs as on here. Same with a Duramax forum. The main reason many 6.0 trucks have HG problems even with studs is that there are simply not enough fasteners holding the heads on the motor. Combine the troublesome oil and EGR cooler and 4 Head bolts and its clear why many 6.0's have blown gaskets. However, if you maintain both a 6.0 and 6.4 they should treat you just fine without studs.

Majority of guys putting studs in a 6.4 is because there gaskets went. Some are spending the money before it happens but most because it all ready happened myself included

Tuned 6.4s with intact EGRs pop gaskets nearly as commonly as 6.0s

I thought the egr acted kind of like a waste gate on the 6.4

I knew it!!! Cylinder pressure kills the head gaskets!!!!!! Exhaust back pressure kills the valve train, and EGR's kill connecting rods, CCV kills piston 2 and 8, and that's it. (Most of these are very rare problems)

I think he means Regen kills 7 & 8...

I wish ford would just put studs in from factory. Does it really cost that much more if they put them in on the assembly line?
