Copper header gaskets

After going thru 2 sets of fel-pro I decided to switch to copper ones. Any pros/cons to the copper gaskets? Also any special precautions I should take when installing them? Thanks

Spray them with some Permatex copper coat and pray.
I never had much luck with them unless the block had been o-ringed.
It has a lot to do with how well your head and deck surface are finished and how flat and true they are.
The MLS (Multi-Layer Steel) head gaskets may have been a better choice.

My head gaskets are fine. It's my exhaust header gasket that goes. But I will keep those mls head gaskets in mind thanks.

The gaskets came with lock washers I guess I'll use them with my header bolts see how that works out. I should get started later in today. Thank you for the compliment.

Hahaha! Sorry, that happens sometimes when I'm groggy and not paying close attention to what I am reading. I completely missed the "er" on header.


As long as both surfaces are good and flat you shouldn't need any type of sealer.
If you ever need to reuse them they can be annealed by heating them cherry red with a torch and quenching them in water.

Yup those are the ones I got. Anyone use any special tools besides a box end or socket? Just trying to mentally prepare myself for when I get started later on.

When using a one piece header gasket, I usually cut the bottom out of the two end holes.
That lets me attach the header with those two bolts and then drop the gasket into place on them instead of fighting the header and gasket trying to get a bolt started.


I prefer the small headed 12-point header bolts. They are much easier to get a 12-point wrench or socket on than the 6-point bolts.
