bolt placement for timing cover/water pump

MT there's nothing you can hurt unless you bottom a bolt out and twist it off. If you feel one bottom out before it's pulled up tight just back it out and try a shorter one. You can get a good idea of what should be used where by inserting one in each hole and seeing how much sticks out before you start threading it in. If the bolt is the proper length there should be approx. 1/2" of threads to screw in.
