I was mounting a new Mummert Ramshorn today and found that on some of the bolt heads, there was too little clearance and my socket would bind up before bolt was seated.  Think I read of other's similar difficulty but dont remember seeing solutions.  Grind down socket, grind relief in manifold, use allen head bolts?  John, anyone?  A "crow's foot" doesnt work either.
