My truck has arps and had 10 miles on it before I started racing it never puked
Aaron blew his headgaskets on his race truck first dyno run hit 100 psi t
Put arps in and it didn't puked
There's a point where h-11s won't handle

Here we go....if it's not a non-vgt vs. vgt or single vs. compound debate, it's gotta be something.

Then how the hell did the previous engine survive 9 second passes, blown up-pipes after blown up-pipes, nitrous bottle after nitrous bottle and no problems, then he puts in a junkyard engine with a set of studs and it pukes the first time? I dont quiet get that... did his truck ever make it back on the dyno after that with the arp's? I thought it went to the track and hurt the motor on a fresh set of studs and gaskets? And we still dont even know the failure on that engine yet...
FWIW i used H-11s never seated them in, never did a retorque and sprayed the *** out of it with less than 50 miles on them... still good even now.

What's the problem with the h-11s? Aren't they supposed to be higher strength than the ARP?
everything has proved that they are supposed to be material wise and based on desired clamping force and percent load on the bolt the math says they should be better...
I would like to know why these trucks with h-11s are failing. No failures untill lately that i know of anyway.

There isn't a problem with them. They have been proven on numerous high horsepower trucks. Look at the abuse that Rudy's race truck went through. That's proof enough.

not that ive got a 6.4 or really high hp, but im on the 3rd time reusing my h-11's. never did the HG's go, its always been something else. i actually bent rods before the HG's blew

maybe a correlation between the number of times they've been reused and the failures?

IF we are counting how many times H-11s have been reused....I win! LOL
Im pretty sure Im at 5, about to be 6.

they were used twice and heads were machined flat like all head jobs we do

I understand that. I would like to see a fresh build with brand new H-11's and properly sealed head gaskets see 80+ psi. If it doesn't hold, then I'll start believing there is an issue. Until then I am not going to acknowledge that ARP's are better than H-11 studs.
