Do you use Permatex Copper sealer on your steel shim gaskets, or do you have another favorite? Mike
Wow quick response 340. I hate to put them on dry and I don't like the idea of silicone everywhere.
I agree with 340plot.
I use Permatex Copper spray, on all my stuff....works good.
My DSM never saw more than 25 psi boost....and the headgasket never let go....course it was a MLS Cometic Gasket and I used ARP Head Studs as well.
