Message: [QUOTE="JonathanN, post: 534847, member: 4486"] I apologize if this has been asked, but I've searched for a few hours and can't find any real solid info either way. Have the 6.4L in my signature and we're going to do head studs so we can run a hotter tune without worrying. We're currently running IDP's street tune... I believe it's between 150 and 180hp over stock. We're gonna probably run the 250 for all-around, hotter for when we feel like screwing around. I'm having a hard time convincing my dad it's worth the effort to yank the heads and have them checked and to be honest, I'm not convinced the gaskets need replaced either. I'm going to ASSUME the gaskets are good since the truck was stock for the first 110K (has 150K now), it's been driven pretty moderate since we did the egr delete w/gate and cat/dpf delete, it's never puked coolant EVER, doesn't EVER get even remotely warm, pulls in excess of 10K quite regularly, etc. I'm game to try something. The only kicker is I live in Kansas and I'm home for the holidays (Virginia... 1500 miles away). I don't wanna do the studs, go back to work, and then have the gaskets go out and it have to be someone else's problem to fix. I hate having other people put their hands in my work. Any input? Cab will hopefully be off in good time tomorrow and the valve train rattle figured out. According to the manual, stock bolts are torqued to 70lbs, then 115lbs, then 90*... the ARP's I have are supposed to be torqued to 90, 180, and 275. If I did one-at-a-time, I was going to use the same sequence and torque to 90 and then 180. Once all the studs are swapped, I'd then do the final 275. It's really no different then stepping up from the previous spec to the next spec in the sequence, especially since I'd be doing them in the correct sequence. Thanks for the help. I'm a mechanic by trade so stuff like this doesn't bother me and like I mentioned, I'm game to try something... any thoughts? BTW, if this was my truck, heads would be coming off. :thumbsup: [/QUOTE]
