flatout copper gaskets are coated so you don't have to use anything. i was thinking of trying a set.

other wise people use mylar to coat the gaskets.

if you do a google search on copper head gaskets. most of the venders have how to install them.

Did Google Search Not Very Much Info On Instal Procedure, Yes Flat Out Has Gaskets Just Drop On, So Does Scr But Both Are About $140 A Set And I All Ready Have Set Of Regular Copper Gaskets.

sorry i told you wrong. it's not mylar it's Hylomar that people use.

the big problem with copper is the coolant leaks.
