I personally have not had an issue with cracking blocks with mulitable stud jobs. Might consider doing sealant but thats about it.

You not worried about cracking the block by doing the studs more then once?

Let him bear the palm who has won it

Why does water/meth not work well on the 6.4s? I've heard that before and always wondered why

I wonder if power has anything to do with it. I am going to try to knock it all out when the heads come off just to be on the safe side.

I don't think so. All of mine were from a torque wrench that wasn't calibrated correctly. Over torquing them. Personally I think most instances of cracked blocks are from operator error. Like mine.

I've been told that alot and that I should just sell mine but when I just had an intake exhaust and my Mini Max it helped. We will see how it works with this set up. I have been given so much crap about it, I will find out once and for all what kind if power gain and temp lose I get when I'm done with this. Just wish I would have already done that because I think it won't be as necessary now so I won't see as much of a benefit.

I could push my truck from 50 to 100+mph at WOT without setting off EGTs on HD300. My other truck I am running a Spartan and the EGTs will go ape chit on a pull from 70mph to 85mph on the 300LL. 275LL isnt bad on EGTs but it doesnt pull as hard. Feels like I can add more air with just a big tune but meth might work as well.

That's exactly what mine was doing on the H&S 250. Keep in mind I didn't like mine going over 1500. After the water meth it would stay below 1500 at the drag stripe after holding at 10-15 PSI for a long time waiting for the other truck to stage. I'd leave at about 700+. My H&S would say 1650-1690 but the EGT probe mounted in front of the #8 exhaust port for the snow kit would only show 1450-1520.

With the snow kit I could go from 0- my speed limiter without hesitation. Raced a Camaro up a decent grade for 80-135 (speed limiter) and never defueled.

Mine cracked within 5000 miles of the first time it seen head studs on a 55000 mile motor i think if its gonna happen it doesent matter......same old second stud from the back on diver side....pulled the stud and filled with a thread sealant and done.....cheap insurance give it the sealant the first time and save the wonders

same here except mine had 85k on it...
