Blown head gasket blues

Well, gotta pay to play. Blew the head gasket on my 12 valve. Coolant POORING out on passenger side. Felpro gasket, stud nuts torqued to 125 ft pounds. Should I torque it more? Thatís the spec that the kit from opti torque said. Should I o-ring it? A local machine shop says they can cut the rings in the head. Or should they be in the block? I didnít get the head cut last time it was off for studs. Checked out nice with a good straight edge though. Iíll update my profile with specs , never dynoed but it rips pretty hard.
12 valve, p pump, 191dv, 5x14 , 18 degrees, 3/4K, 60lb springs, S362.
Nv4500 / 4x4/ Fummins (89 f250)
Thanks in advance, this is the only forum I bother dealing with.

Oh, this thing buries a 35 psi boost guage. I’m guessing 50 . It gets rowdy. . Also, I don’t tow or daily this truck . It’s just for fun.

Get the head surfaced, then O-ringed.

Try to get 135 or more on the studs, get them up to around 120lbs, then 5lb increments after that with long breaks.

You will have no more worries of head gasket issues after.

Also you said it's making 50psi, need to run more timing.

I'd bottom tap if you haven't already before going crazy on the torque.

Yes, borg Warner s362 from power driven. Is that weird? It spools pretty quick, seems ok? I did bottom tap when I put the studs in.

He’s asking for the turbine specs. 362/68/14cm etc.

If the head comes off once then it’s getting o ringed if it’s mine. Cheap and more reliable. Less of a chance of head coming off a second time for the same issue.

Bump it up 3 or 4į from where you are now for a start.

Especially being a stick shift, it will pull through the gears and Rev out farther.

Low timing will make abnormal High boost psi.

I'm no Weston, but have always preferred a larger hot wheel. I'd go to a 71 or 74 turbine if you wouldn't mind a slower spool.

Or the .83 housing with the 68 wheel would spool like the 14mm and have way more top end powa

Appreciate the info guys, when funds allow I’ll definitely try out some different turbo geometry but for now I’m gonna bump the timing up and see how it goes.

A 62/68/14 making over 40psi of boost on a mild 12v,
I bet he's running a real 16ish timing.

Put a bigger turbine or housing on this stick shift truck, it will be a turd.

Might want to look into a boost gauge that you don't have to guess what psi you're actually hitting.

Why was this gasket installed in the first place?
I'm skeptical it's tuneup related.

It was the most readily available at the time, lesson learned

I did, never expected to make that much boost when I started this project.
