What head gasket to go with for HIGH boost??? I was wondering what head gasket to go with for my turbo motor. I Have 6.0L truck heads and plan on running around 15# of boost on the street and around 21#'s at the track on a 370 iron block. Also what header gaskets to use as well. Any insight from some of you guys would be apprciated. Thanks
The mls gasket works great!! We did a first head gasket check on Mike Browns CE and liked what we saw. Just get your heads O-ringed and run good fuel when boosting above 15 and a meth kit wouldnt hurt either.

stock 6.0 mls, the stock gaskets for the manafolds next tot he heads, and high temp rtv for the triangle flange on the manafolds.

For other reasons I hate thinking about, (not gasket related) I have installed these gaskets two different times with no leaking or problems first try. The MLS tri-metal design is thin enough to "form" itself into the grooves. When you take them out it's clean and they look like they were made for it. I also have heard they have held up quite well without o-ringing too. Good luck.
Well when I talked to Brain Tolley of TEA he said no way. Thats is what I based my opinion on. Here is what he has said in the past about it. And since I got my first set of heads from them or was suppost to (Long story) I took his word.

May make a difference if you have receiver grooves in the piece opposite of the o-rings.
I have only o-rings in the heads, and no corresponding groove for the metal gasket to distort into.

The ICS Titan head gasket was installed without sealants, o-rings or
receiver grooves. Pressure transducers were mounted at the gasket and data sampling occurred at a rate of 120 times per second to confirm that there were no coolant or combustion leaks at any point in the tests.
A closer look at the numbers shows that the new ICS Titan head gasket sealed over 6.4 hp/cubic inch at an estimated 3300 psi cylinder pressure. We were as pleased with the performance of the new head gasket as we were impressed with the colossal horsepower of Kenny's "little" engine.

,probably 20 passes for fun at the track, and a couple dozen dyno pulls. I'm sure there is a limitation to what I have done, but I'm loving the hassle free set-up for now! 
OK here is my setup.
Ported 5.7 heads with O-rings. Old set off Formula.
6.0 MLS gaskets.
LS2 block no modifications.
Off the shelf ARP studs.
I clean both surfaces and clamp em down.
I ran this combo all season on one set of gaskets.
At the end of the season I was up to 27psi max at 21 timing. They leak no water. I do push some water on each pass but this seams to be the norm at this level. Thing is they could have stayed in longer but wanted to check things out and start fresh before going to Florida.
I'm just telling you what has worked for me. Will it work for you? I don't know. But this is the same setup we will be using on the Formula when we replace the iron block. Cheaper then copper and no silicone mess to deal with.
Good luck.
