i have had 3 3mm InlinePro head gaskets. Each head gasket has lasted 20-25k miles. This equates to 1 year of DD the car. Each time the head is removed it is decked and checked for straightness. First time the head gasket was installed, it was done by billman250, a well respected Metro member. That head gasket had no copper spray and lasted about 20k miles. The second head gasket was installed with copper spray and lasted about 25k miles. I just changed my own head gasket for the 3rd time and didn't use any copper spray. InlinePro's prerogative is that its a bad tune that is causing the head gasket's to fail, while my tuner believes if it was a bad tune, it would have failed within the first 200-500 miles, not 25k hard miles. Next time the headgasket fails, i will either give this headgasket a shot, or finally go built motor with a stock HG so i don't have to worry about it anymore.

 

^ Excellent feedback. Now I am no expert on tuning, so pardon me if I sound innacurate. But, Wouldn't a tune that promoted excessive combustion pressure make this HG more prone to fail compared to one that had more conservative timing numbers? Just a thought...

 

I have a SCE ICS Titan on the way.

I talked with SCE and they recommend that you use a syringe to pipe out Permatex Mega black sealant onto the gasket. Install the gasket heat cycle the engine and retorque. When retorqueing, back the bolt off 1/4 turn then torque to spec.

So that being said what is the recommended torque with ARP studs and does that take into account for lubricants?

Should I use the KW Copper seal and Permatex sealant?

How do you prep the block?

I ask b/c my intuition is that failures to perfectly execute the above items are what causes failure and are exaggerated by the thickness of the gasket.

 

bump!
ill probably be going with a head gasket later in the year so this is a good start~discussion.
anyone else got feedback with the inlline gasket?

I think he has a few aces up his sleeve, he is sand bagging us.

 

Nice find, If these work, sign me up for one. Im about to do a 2mm cometic, but it looks kinda hokey. I looked at the layers they used to make the correct spacing. In between the layers it looks like they took a random orbit sander and smoothed it out, not exactly precision. Its just some sheets of aluminum, I think its a 22 and 20 gage piece stacked up to make thickness, with 2 embossed steel sheets on the top and bottom. So in between the 2 aluminum sheets there is nothing really to stop exhaust from escaping other than the torque of the head studs. I imagine this area is the first to leak. Ill post some pictures on thursday.

 

Well mine should be here in a few weeks. I will get some pictures and reviews then.

Yes I have an "ace" up my sleeve. (Inline pro kit which is not installed yet)
I hope this gasket works out well.
