  1. Climbanyhill is correct, BJ's require less maintenance, and are quieter.

     

    However, this does not mean that they cannot fail like the above picture. The only way to prevent that would be to-

    1) place the heim in double shear, capturing it.

    2) using a safety washer over the head of the bolt.

     

    The benefits of a heim over a BJ come in, to me, these three areas-

    1) double shear possiblities

    2) off the shelf replaceable, since you're just using a bolt there are no tapers to match

    3) more articulation when used in combination with a hi-mis spacer

     

    Uniballs are tougher heims. They, unlike the other two, require a welded-in cup, so no adjustments there. On the flip side, the cup is reusable, you only replace the bearing itself.

  2. it really comes down to the cross hatch. you could get a more coarse cross hatch which you have to be carefull not to make the rings cut too fast, or you can get the newer finer crosshatch, in which case, you get in your heat cycle to torque the head, and then go strait to plug chops, to verify the jetting isn't doing harm, and to steat the ringsto the best possible seal while they are still realitively sharp enough. the hard loading will press the rings into the cylinder with more pressure.

    This is a very good reply.

    i could send them off be out say 450 bucks and have some awesome jugs, or i could do them my self spend probaly that much in tools and alot of time porting them but i will have learned alot about portng and how they flow and all that.

    That is excellent. . . right up until you make your intake divider a little too thin and it relieves itself into your cylinder head.

     

    If you're gonna do it take it slow, slow, slow.

  4. So if your building a drag car then you would weld and regrind your own camshat so you could say you built it your self? Or would you buy one that is already machined.

    Psssh, you don't own a cam grinder? Some mechanic you are.
