Head Studs

[DrwKingRanch]

After much debate and a lot of reading i decided to purchase the spartan tuner, 5" dp back straight pipe and S&B intake (plastic cover is coming off)

my question is, has anyone had head problems running this combo, and if so is there a head stud kit being offered that i dont know about?

I may be wrong but it seems the rods and turbo are a lot bigger of a issue.

My diesel guy said the head bolts weren't a problem on the 6.7's, they are handling 30+lbs of boost with out any lifting. I would set your defuel somewehre safe tho just for peice of mind.

Yeah, never heard of head stud issues on the 6.7.

One time, one company had connecting rods get ripped apart after adding a bunch of HP. I have yet to hear about anyone running stock turbo, and H&S or spartan having engine problems. Yet....

I remember reading one thread where a guy running spartan tuning bent rods and wrist pins. That's the only thing that comes to mind though, besides turbos.

If you come across it again, please send me a link. Or post the link in this thread. I have not seen that one.

I hit 30# of boost all the time. Especially towing. Tuned6.4 though. I'd be defueling all the time

I am confused. Who are you talking to? And what does this have to do with head studs on a 6.7?

I love the 6.4, tuned it is a beast. My questions for Smokey are legit. If you have no help to offer the OP why are you here?
