Do you have a pic of the thread Chasers that broke? I'm curious what the fracture looks like in case I ever run into the same issue.

I've never run a thread chaser before, personally I use an old head bolt and cut "flutes" into it and then I just running in and out in and out in and out cleaning out those flutes each time. Blast some solvent in there with a vaccum line in the bottom to suck up any crud. Works well for me but it sounds like your threads were throughly caked with shiiit.

As an aside, it's funny after all the posturing and smack talk none of us advice-givers got the issue correct. :)

It is interesting that you torqued em too spec and it lifted enough to let exhaust out/coolant in.... I wonder if b/c you only had 50% (or whatver) of the threads engaged that they somehow stretched enough to cause issues. At 34 PSI it wouldn't take much to cause problems.

Glad you found the issue though.
 
It's not fixed yet buddy.....

I know. But this was without a doubt a HUGE part of it. the head was barely being held down if at all by some of the studs. I'm feeling more confident. Well say that.

@donniekak that sounds pretty useful. I was going to cut an old headstud, but I felt as though if I try to cut any corner it would go wrong LOL.

Some of them were not even holding the head down at all. Which is scary. And I don't have a pic of it and I returned it to summit. But one of the flutes cracked in a different spot than the rest. It was a little lower on the tap on that specific flute. The rest broke up high. You could see where the metal twisted in that area.

That is weird... So the flute kinda broke off then?

So your head was loose as balls then hey? I had the same issue on my first ARP headstud install.... Studs werent all the way in from crap in the threads. Did the cut bolt method and got a ton of crap out of it. I prolly ran that bolt in and out 20 times per hole before it was clean.

Yea it was bad. I assume I was basically torquing the head down with the stud per say. The nut would bottom out, and the spin the stud more til it was torqued. And yeah I got a lot of crud out
 
Well the car is up and running again. So far so good. I haven't lost a drop of coolant yet. I also haven't went WOT since the new head gasket though because I need to get it tuned. I have to fix an exhaust leak and do a boost leak test first. I will be getting it tuned hopefully this week sometime and then I will report back after that. I am pretty confident that it was the ARP studs not being bottomed out. The tune probably didn't help, but I don't think it was the major contributor.

I'm going to shoot for 30psi when I get it tuned and keep the timing conservative. If I want more power, ill add boost. That seems to be the more safe option.
