Yeeesh. I have never done that. In your case, I think that I would also consider giving it a try depending which bolt that it is. If it doesn't work or leaks worse after you're done, the head will need to come off anyway. On second thought, knowing me, Id pull that head and fix it right...

Did you put the ARP thread sealer on the studs that go into the water passages?

Hmmm, did you use ARP studs? Torqued to 80/80/80? Felpro 9333 gaskets? I'd honestly pull the head and redo it. Best case is you fix it, worst case is you've got a warped head...

No uppers 70 lowers 60 as per arp calls for on 7/16 studs and coolant coming up from the water jacket probably just means I didn't do a good job sealing it or theres an issue with the threads and heads are fresh from machine shop I just chased treads and resealed the one stud ill let you know if it worked thanks

Three equal steps of 80 ft lbs

Direct link to the ARP 7/16 head stud kit instructions on the ARP website. These are the torque values I used when I did my motor and had 0 issues.

Glad to hear its sorted out. Did you torque them all to 80 or just chase and re-torque to what you had? They'll most likely be fine at 60, they used to be spec'd for that, not sure why ARP changed the specs but w/e.

Ya just the one check the rest all good left at 70 and 60 dasilva racing also suggested this spec or 80 and 70 but they said at at point you're just stretching the bolts. They only clamp so much. Thanks for the input👍
