They have a 50% crush rate, 100% graphite and no re-torque needed

Yes, Remflex gets great reviews and I only read one bad review.

The fact that it "crushes" may be what causes it to leak... but I have no idea how someone uses the gasket, what gasket sealer they may use, or the condition of the header, the exhaust manifold, so I read posts and statements with some degree of skepticism.  One thing I have learned from being on these public "auto" forums since 1999 is there is a wide range of knowledge, experience, and Bravo Sierra.

Regarding retorquing header nuts.... If you don't check the header on a 22, and keep it properly seated against the exhaust ports, regardless of what gasket you use, it will tend to leak.  All three of my Toy truck with 22s have leaked at the exhaust. 

In my experience there's a tendency, over time, for the studs inside the head to corrode, powder, and spin. The different coefficient of expansion between the alloy head and the hardened steel studs causes this. The self-locking factory nuts cause too much torque on the small number of threads inside the soft head when torquing them.  I've posted this before.... I don't use the stock factory self-locking nuts.

I use a lock washer, hex nut, and hex jam nut.  I use red Loctite on the head threads, and anti-seize on the header threads.

I will check and retorque the nuts after an install 30 minutes after firing the engine. I will check them again around 50 miles and 200 miles.  If they are tight after around 200. I will check them again at around my 3K mile oil change.

That's just my worthless opinion.
