How far on stock head bolts?

What is the farthest they have been pushed without failure? I have a 2003 6spd EGR delete with 175/75, MTW hybrid, RR, Matt's tunes I run only the SLR tune and a FICM tuneby PHP. Been running this setup for about 20k towing and lots of hyw with no issues and those are hard miles. I will be installing 225's and a stage 4 soon and studs cause I'm not completely crazy. But it would be nice to see how far I could push them stock bolts.

That's probably the most power I've seen thrown at stock bolts and it not blow a gasket. Ford must have put some nice flat heads on yours from the factory.

Btw, what do you run the FICM tuner on usually?

On my old 6.0L, I had it pushing close to 500HP on stock headbolts.

I was just getting ready to start a new thread asking who has the most mods on stock bolts.... you beat me to it! haha

I've got about 30k on SRL+ and various MTW and Pmax turbos, blue spring, EGR delete, and a 5" exhaust system with no cat but a muffler big enough to make my truck lean!

Sounds like your about to find out for us. Let us know. I can't understand why, but will be interesting. You've been that deep many times to get to the injectors, don't know why another $500 dropped on ARPs don't outweigh the $10k you will have to spend when she grenades. Oh well, pay to play!
