What the COMPRESSED thickness of the 2.5s head gasket? After I torque the head and take it out it's around 1.7mm but I am sure it's thinner when under the torque of the headbolts.

I am having some thicker headgaskets made up for my new 2.5 and need to calculate the needed thickeness for the desired boost level.

Thanks,
Greg

Ive always measured 1.7mm Greg.

Thanks Barry,
I would think it would be thinner then 1.7 since that's what it is when removed from a running motor. Still, I will go with that number and take accurate compression ratio measurements before and after the thicker headgaskets are in.

What's the compressed thickness of the Headgasket?
