    Hello Gurus, I used copper gaskets on my 509 with a 871 that I now know shouldent have. They leak and I need to know what to replace them with. Heads and block are not machined for O-rings, only plan on 5lbs. this summer maybe 8ish later on max.
    8.4 comp.
    What should I run thats trouble free?
    Thank you!

    Superdave013 recommended the gaskets they sell at Clay Smith Cams. I bought some to replace my copper gaskets with. They call them Detroit gaskets. I have not run them yet but am sure they will seal with or without "O" rings.

    A bunch of us run FelPro head gaskets with the built in wire ring on our blower boats. All run 8 pounds boost. No problems in a year, knock on wood http://free.***boat.net/ubb/biggrin.gif

    Thanks for the responses. Another question would be what type of gasket sealer are you guy using for head and intake? Especialy intake since I cannot properly torque a couple of the bolts.
    I just removed intake and it looks like I ran a ton of water through the motor. It has about 1 hour on it including cam break in. Dipstick never looked milky untill the very end of my little test session.
    Cam looks great, I don't want to pull the motor to clean it up. I am hoping that maybe I can get away with new lifters and many oil changes in the driveway. Any thoughts?
