Hey .. I am researching head gaskets. I want to make sure I put the proper one on my car. It is 11.1 c/r with twin 62s, will max out mid 20s on boost and e85. Will be on the street a lot so which head gasket is a good one for my set up? I do have arp head studs...
Head Gaskets
- Thread starter termcobra281
- Start date
Felpro MLS gaskets is what I use
Part # 26222PT (right)
Part # 26187PT (left)
My last motor was around 800hp, my current motor should be more.

Thanks I will check them out.
How does anyone feel about the
Cometic MLX Head Gasket
I run cometic gaskets on mine. With studs, I run 22 psi on the street and have a 26 psi setup too. No issues, been on here for 4 years now. My CR is 10.3 too.
These are the part numbers I run.
C5118-040, C5119-040
My block has been decked twice, so my pistons are proud 0.005”, so the machine shop recommended 0.040” thick (0.035” after assembly) for my setup.

These are what I use also. Nearly 40psi
Sounds like either the MLS or MLX will be fine.. thanks
Looks like they are only 40 a piece also. Thats a good deal.
@badcobra
I’m sure you’ve answered this a 1000 times but what did you torque your head studs to? I’m running the same gaskets as you per your recommendation.
Thanks
Ken
On a teksid block, I torque to 100 ft/lbs
By the way I forgot to ask, does these gaskets require you to retorque them after so many miles?
I am also doing a head stud upgrade.
I was looking at the Cometic gaskets but being stock block what gauge should i look to purchase?
I see the have several in the
30
40 ranges

Stock is .036. Gasket thickness should be dictated by your piston-to-valve clearance….if youve had the heads or block decked you may need a thicker gasket.
Yes stock size and stock pistons.
Will it hold is the other question lol.

Felpro here as well, almost 30 pounds torqued to 75-80 ft/#'s. Next time i will do 85 to 90 ft/#'s
Romeo iron block suggested torque is 100ft/lb…for aluminum blocks 85 ft/lb…you can go more but could potentially fracture the block - its happened to others.
Just ordered from Modular Head Shop
.40 Cometics
