    Agree with HRK 100%, Those paper ones won't last,they were junk on Evos and Shovels have a little more "shake" in them than an Evo;)
    Good quality gaskets and locktite and you can have a leak free Shovel.
    Had a '76 FLH years ago built for torque,the only leak it had was the chain feeder,so it still got to mark it's spot:D

    They sure do like to mark their territory LOL. OK, fellas, I'll search around some more. Tattoo took one look at my gaskets, laughed, and threw them in the trash! I had Cometic ones the last time and had no problems.
    Tranny still leaks but that's another issue :arghh:.

    I have a set of steel Cometic base gaskets on order from J&P that should be here any day. Also have a new front exhaust rocker arm & shaft on the same order. Wondering if I'll need to get the rocker arm reamed to fit the shaft . . .

    I do have one question: what's the torque on the base nuts? Nothin' in the book about them. Last time I just tightened them by guesswork and they didn't leak. I got lucky . . .

    If the rocker arm rotates freely on the shaft,you should be good to go,if it's tight or binds then ream it.
    I did a little search for torque specs on base nuts and found 35lbs is spec but a lot go to 40lbs and recheck after a couple of heat cycles.
    Don't take those specs as fact though,it was an innernet search I did,no actual experience myself. The '76 was done by a Pro and I sold the '79 before I got into it.
    The guys on Shovelhead Forum should be able to give you a definite answer.
