Sorry for this off topic hijack, but I can't post a WTB ad, it won't let me type in the box even though it says I can post new threads. Anybody?

Yep, he is "demonstrating and showing off their new 1/2" headstuds". I was always suspicious of this test, just because it kind of plays out like an infomercial.

I have used the same ARP 625 set for seven years with three blocks, always on a 29-35psi setup. I even ran stockers on a 27psi setup for a while before I got a 2011 STI. I think "head lifting" has more to do with build and tune quality. Get greedy with boost and/or timing, you are gonna pay.

I bent one of my 625+ headstuds when I lifted a head, all torquing procedures done properly, arp lube only where it was supposed to be
I am looking into 1/2 options, and debating to just beat it and go straight to 14mm |

Also stu do you have any build thread or something with dyno of the gen 2 gtx3582r? Thats a good one.

I mostly road tune my car myself but at some point when it warms up I will head down to Harvey's shop here in C0. Ive had the OG 35r HTA86, Gen 1 GTX, and now the gen 2 and the gen 2 is by far the best variant of the 35r series. I'm having traction issue(255 40 18 so4's) in 3rd,4th as it is, but when its cold out its scary on anything over 33psi. The gen 1 gtx wouldn't start spinning then until 40+

Sounds like a major handful! Yeah in the cold it gets way crazier traction wise, the rubber just hardens up so much. I also had the hta86 at one point, really enjoyed that turbo.
Any road dyno or anything from the road tuning? If not no worries just really interested in that setup, sounds legit. |

The gen2 hits the hardest and there really isn't much of a difference in spool up. My data logs show 37 psi at 4500 rpm in 4th. Im not to worried about dyno numbers and I really like to do real world tuning especially at my altitude 6900 ft.
This is my current setup. |

EFR7163 @ 5psi I had my engine fail under uncommon circumstances most likely due to excessive cylinder pressures and loss of one coilpack back on the topic how does one find out (other than the practical way) if a given HG is compatible with o-rings? I am thinking of o-ringing my heads (because I use stock cylinders) and not sure if JE MLS HG will play nicely with them |

I believe that is why IAG moved away from the o ringing because they didn't work well over time with the MLS gaskets.

Bought new fire-lock gaskets from IAG https://www.iagperformance.com/IAG-Fire-Lock-Head-Gaskets-1-Pair-p/iag-eng-1740.htm and tried to contact support because in description stated that prior to install machine work need to be done, about almost a month I can’t get clear answer what need to be machined prior to install, after some research I found that counterbore step on block need to be machined, I wrote to support to specify dia and how deep it should be machined, and how do you think what they answered? That I need to ship block to them to do machine work and they can’t provide such information because it’s proprietary process!!! What a f*ck, I’m from another country and shipping block to IAG and back will cost me $2000+. We can do this tiny counterbores in-house on our cnc, just give me numbers! I understand that ring itself are made from IAG spec material and are proprietary, but the numbers on how to make groove for rings need to be provided, otherwise what for they sell this gaskets to public? Why there are no info about machine process that need to be done ONLY by IAG on product page? I’m disappointed in IAG and their support team , that can’t answer questions, just send invoices
And because of that I had a question, what company makes headgaskets that will not fail on 3+bars and have not such bs with proprietary process |

that's perfectly normal
I believe I have sent them about 7 emails in the past on various support topics, and the only thing I ever heard back was their automated response system saying how important my email is |

Shoot me an email at [email protected] and I will get you the specific details you need. There are a few reasons we don't normally provide this info, but in short, the counter groove depth, and diameter is only half of the puzzle. The head stud size and torque is also very important to ensuring that these gaskets/rings work correctly together. This also means that the block MUST be torque plate bored while gaskets/rings are installed and the case torqued to the same spec as final assembly. This means you need a second pair of gaskets just to hone the block. (because the silicone on the gaskets is pretty much one time use) The point is, it isn't as simple as it seems. I am happy to walk you through it however. My apologies that our support team didn't get you the answers you needed. Regards, JJ@IAG |

My suspicion is that you have the cooper/willis ring version. This does not require any machine work. The new Fire-lock version however does. It can't be installed without machining a groove into the block. Regards, JJ |

Are you able to help me as well? I have the IAG Extreme short block with all the options, and also a built head with +1 intake/exhaust Ferrea valves and BC Stage 3... By IAG suggestion i used the Cooper fire version with the 14mm IAG studs torqued to the spec described in the manual. I run a GTX3582R and i feed the car E100 using 8x 1700 ID injectors. All fine and good, except the gasket hasnt lasted one lap on the Interlagos circuit (Brazil) at 2 bar. It even started leaking at 1.7 bar. Water did not get past 100c...oil did not go past 110c. All logged and checked using Motec. Then the car spit water in the windshield and started spittinf liters. This is my second gasked attemp, first was a Cosworth gasket on the Cosworth shortblock. I contacted IAG and they said my current shortblock would not work with the new fire lock because of distortions when it is torqued for the gaskest. Adam is helping me with information, but i think it is a bit confusing. Could you explain better here? Can i use the current shortblock to install this new gasket? Is it expected to be much better than cooper version? Or even double oringing? Im trying to build a race STI, got everything else working (sequential gearbox, dry sump etc)...but cant get an engine to run a full hot lap at 600 whp! Please advice on the gasket situation! |

From the sounds of it. You need the older cooper ring style. Thats what you need if your block has a standard decked surface.
If you use the newest style Fire-Lock gaskets. Your block needs to be machined of them. They also require the use of 14mm studs. Also, just thinking out loud. If your block wasnt machined for the ring. Then you use the ring without the recess in the cylinder deck. Torque the heads down. The cylinder are going to distort in a major way. The newer style ring would keep the heads from actually mating and sealing tightly. I would suspect coolant flying everywhere as you described. I also think there "could" be some pretty nasty marks/gouges in the block and or head surfaces. from the ring taking all the load/pressure all by itself.

Have IAG 14mm torqued to the specs described on the manual with the cooper fire. Leaked at 2 bar with less than 100km. Now spitting about 3 liters of water per lap on the interlagos circuit. 2 laps, 7 liters, plus overheating from the gases going to the radiator/temp sensor. |
