Flatout Gaskets
Flatout Gaskets I see a couple of you guys are running the Flatout Rubber Coated Gaskets and wanted to see how they've been working for you. I'm building an LT1 stroker, (389 3.800 x 4.035), that I want to hit with the juice. My block has been o-ringed and I've heard about a lot of coolant leakage problems with copper gaskets, especially on mostly street driven cars like mine.
Help out a lowly LT1 brother, who just wants to try and keep up with you guys driving "God's Motor" and let me know what your experience has been with these gaskets on street cars.
Thanks.

ZAngel's gaskets are sealing well so far, NA only. Haven't put the boost to it yet, since her turbo is still sitting about 20 feet away from the car right now 
She's put about 1000 miles on 'em so far I think.

Mine came up after 9 lbs of boost even with o-ringing. Had to switch to 6.0 MLS's on my 408. Could have been a bad experience but I have heard others that have leaked as well. Stock gaskets worked pretty good up to 10 psi for me on my 346.

The only reason I'm considering it is because the block already had o-rings in it when I bought it. Is there any other type of gasket that's compatible with stainless steel o-rings. I believe I've heard of guys running a composite gasket with block o-rings but I'd really like to hear that from someone direct.
