Stock isn't paper, stock is multi-layered steel.


And that's my vote. Sealed perfect with my Pacesetter's.


I know friends who have had great results with Percy's, but they're kinda pricey.......

GM MLS are the best. I did use though after I found out Dynatech's gasket, which is also MLS but is directional which made it a PITA finding the correct orientation.

Either way MLS all the way!

Agreed GM are the best. I still use my stockers. Just clean them up some & if they are in good shape then your good to go.

heres my honest opinion


New stock GM gaskets, are pefect. not a damn thing in the world wrong with them. They are cheaper and are proved time and time again to be fine. If you really wanna fork out the cash for the percys for peace of mind then go for it. Its really not neccesary, but you cant put a price on peace of mind.

Personally, I used stock GM gaskets and had no problems.

Stock GM is where it's at. I re-used my stockers with zero problems.

2 header sets and 3 stock sets later, I switched to Percy's and love them, no leaks at all and reusable for life (so they say).

RevX reused my stockers. As long as they are in good shape, they (and I) don't see any reason to replace them.

You're on the right track with metal gaskets. The stock GM's are great, but they're also very rigid. This makes them unforgiving for uneven header flanges. I got the Percy's aluminums to be on the safe side. They're multi-layer soft aluminum so they conform to any irregularities.
I'd stay away from copper due to possible galvanic corrosion with the aluminum heads, but that's just MO.

The stock header gaskets is one thing GM perfected. They can't get any better.

I vote for Percy's. I re-used my stock gaskets and they leaked, even though my headers have 1/2" thick flanges. Went to the Percy's and so far so good.

I have used the GM Gaskets and have had no issues.

I got GM gaskets are they sealed really well with my pacesetters So my vote is for the GM's....although I've never had the chance to try the others.
