I have a header gasket leak on the passenger bank somewhere so it looks like I am off to autozone tomorrow. Are those layered aluminum gaskets worth anything or should I go with copper/other?

I have had good luck with the multi layer header gaskets from the ZONE haha
BUt seriously they work pretty well on my nova
you can even shave the ports pretty easy if they dont match up well enough

I have always had good luck using just the individual exhaust manifold gaskets on headers.

Looks like what Al is talking about is header gaskets made the same way as manifold gaskets. Looks like the ones I will buy!:yes: This engine bay is getting mighty hot already!:eek:

Are the steel core/silicone lined valve cover gaskets good too?:D Mine tend to leak just enough to get the motor dirty.

I had a terrible time with mine until I bought a set of the copper ones from Summit.I put them on then after about 100 miles I tightened them once more ,no leaks and that was four years ago.

I have had luck with most types of laminated gaskets, even OEM manifold gaskets hold up rather well.

I have had good luck with both the copper, and the aluminum gaskets. And yes, I have sucessfully re-used them.

What I like best, is that should you develop a leak, they don't blow out like the paper gaskets.

My Sanderson headers have machined flanges and all they recommended was the hightemp Permagasket or similar type sealant - no gaskets. No leaks/ no issues here without gaskets.

Suprised the crap out of me the high temp stuff holds under the heat but it does.

#8 and #7 header bolts were way less than finger tight. Might explain some of it!:eek::D Same thing with my #1 intake port-thingy leaking oil.:bored:

a good idea is to retighten the header bolts AFTER you install the headers and gaskets and run them thru a heat cycle. Often times people will go tighten them when they're hot and when everything cools the bolts are loose.

I've been using the Percy's aluminum gaskets, and no leaks for the past 8 years, I bought them from Summit. I just make sure the header bolts are retightened ( if needed), after about every 20 or so heating/cooling cycles.

A lot of the reason header gaskets blow,

is the bolts get loose, and the hot gasses eat the gasket, I have a set of locks on my header bolts, they are simple pieces of aluminum, with the 7/16th hex cut out, all except one side, get it hot, let it cool, retorque, then you slide the collar over the bolt, and put a snap ring on the end of the bolt ( they are machined for the snap ring ) and even if they TRY to back off, the aluminum collar wont LET them loosen, never had a leak since.

For headers, I usually go back and tighten them up after the first three drives at least.
