Header Gasket Help???!!!
Im on my 4th set of header gaskets on my 95 TA i only have 1700 miles on the engine and headers. I know my flange on my headers is not warped because they are LPP headers and are about a Half inch thick. I installed New Copper gaskets because i heard they were the best.. . . . well im leaking from both sides now instead of one..... i heated them up by running the car for a bit then cranking them down. Ihave done that 3 time....still leaking.>....... any advice?????

Copper gaskets suck. I've never ran locking bolts and everything has been fine. I bought some stage 8's a long time ago but they looked like a pain in the *** so I returned them.
Even though your header flanges are thick it doesn't mean they are truly flat. Check them with a strait edge to make sure. A lot of people have had good luck with felpro gaskets I can't remember the part# of the top of my head though, I'll quickly search and post it.

Get Felpro 1406 gaskets.
Tighten bolts. Make sure you tighten them after a couple heat cycles. Then tighten them again after a couple more heat cycles. Do this like 5 times. I just use regular header bolts with lock washers. Not stage 8 bolts or anything like that.
If that fails you can try putting red rtv on the gaskets.
If it still fails you have a warped flange (or head), a crack in the header, or another problem (loose rocker or lifter noise or something).

I had a hard time getting header flanges to seal until I found these gaskets

Percy's aluminum crush gaskets are what I use. Never had a leak.
Also, I dont why everyone uses ARP or any of those crazy expensive header bolts. You dont need them. All I have EVER used is the $7.99 set of MR. Gasket header bolts at any parts store. I love em. Never had one back out. You just gotta know what your doing.

Same here, 1406's for 6 years and never a leak and thats with std header bolts. As for the heat cycle I checked and or tightened mine everyday before starting it for about a week or more. When you can't tweek them anymore then you're done.

You guys that keep blowing gaskets - have you checked for damage to your headers and loose rocker arms? Loose rockers sound just like a header leak.
I had a "header leak" that drove me bonkers. I changed the gaskets IDK how many times. Eventually my friend kept telling me "you have another header leak!!!". I popped the valve cover, found out one of my rockers for #4 was loose, I reset it to whatever past lash (can't remember what it's supposed to be, lol) and never had a "header leak" again.

These have worked great for me, put them in and go, no need to re-tighten. They have replaceable inserts so you don't have to buy the whole thing if you ever need to replace them.
