    Not stupid but if you want a stupid answer that would be torque till you pull threads or break a bolt thenback off ten pounds
    American std on grade 8 bolts is 110lbs. manifold torque is 35 on cast iron and amercan std for a grade 5 bolt is 30lbs. M

    No. Just torque them. Be sure they are clean and oiled. Put a washer under nut.

    Before you put the pan back on...spin it over with the studs and make sure it still turns. I've had a few blocks that twist a cap when bolts are replaced with studs. Remember, you're putting the same or more torque value against nice polished fine threads on you stud kit instead of nasty coarse threads in the block. Your 110 ft/lbs will result in significantly higher clamping force with a fine thread stud than it will with a coarse thread bolt....it will always distort things differently, and sometimes it'll make the crank not turn.

    If you're using arp studs, torque specs can be found on their website. Different thread lubes require different torque specs.

    It sounds like your changing out the 4 stock main & the oil pump bolt for some stock type with studs on top for a stock type windage tray? If so I would suggest changing them 1 at a time. If you want to look at the bearings hold the two bolts about 1 1/2 - 2 inches out of the caps and gently hit one to the left or right to lift the cap off. And lube under the new bolt heads.
