X1million!! wont use anything else! ever!

 

My percy dead soft leaked bad. That explains my way rich problem. New headers, straight flanges and tight bolts and they still didn't seal correctly.
I have ssen the earls, that'll be my next choice. A little pricy but if they don't leak, they'd be worth every penny. Plus the inserts are replaceable.

Stick with the Earl's. I used them twice, 1 time new, 1 time with new inserts. No leaks either time, even after cracking 1 of the new inserts while cutting it to match my ports.
Percy's dead soft aluminum weren't so good for me, I had to retighten the bolts 4 or 5 times and they still leaked a little.
This was on JetHot/Hookers.

 

the only funny thing about those earl gaskets the inserts are only about 10 dollars cheaper than the whole gasket itself. at least through the guy I got them from.
