    Re-Using Head Gasket and Copper Spray

    What is the best way to go on a 1390 motor? I pulled the head to check the wash and would like to put it back on correctly sometime over the winter..

    Will it seal up with my current 2 layer 1200 gasket (middle layer removed) with some copper spray or should I pony up for a new bored 1390 gasket from GroupK?

    How do you guys run them?
    Thanks!
    Doug

    Dont use copper spray.... Buy new ones or install with a thin layer of grease on them.

    ??? I've done this many times. Is it something unique to 1390's?

    Grease? On a used gasket or only a new gasket? Any particular kind??

    Also, anyone else sell the 1390 gasket? I know Groupk does and it sounds like Lowell does. Any difference in gaskets/machining? How's the best way to get ahold of Lowell?
    Thanks

    I use grease on all my head gaskets. I had the 1200 off 3 times and it still looked good. I have never had a leak on the head gasket. I installed the 1300 gasket on my new motor same way.

    If you are buying a new one get the 1300 gasket cut for the 1390 it has better water routing. Lowell has them.
