Anyone using Percy's "Seal For Good" aluminum header gaskets?

I'm using them, and they work. Anything in particular you want to know?

Just wanting to know if they are worth the $$. I'm tired of replacing my Felpros.

When I first took the Percys out of the package I started laughing. I suddenly understood how they could claim to be leak proof. Each gasket is actually 4 thinner gaskets pressed together, making one thick, soft gasket. Well worth it.

Sounds like a good set-up. I've heard the copper ones are awfully good too. I'll soon be trying one or the other. Got a link for the Percys so I could check them out? Years ago I used to ride 2 stroke dirt bikes. My Yamaha mechanic told me I could use the copper head gaskets over and over. He said after a few times of R&Ring it you could just heat it up with a propane torch, let it cool down and still go on using it.

I tried a set of copper header gaskets when I was running shorty headers, and never could get even close to a tight seal.
