Eljaro I will send a letter on doing this between snow storms. How much did they remove from the heads?? the angles could be getting out of spec with head and block cuts. The intake may also need to be trimed or the block on both side of the lifter valley ends. Did you spray the SCE gaskets with Hi-tac or copper sealer and let them dry? The other thing was putting a thin coat of GREY rtv around any water jacket port and any bolt that goes into a coolany jacket hole. As far a
oil, you want the valve springs flooded in
oil. The max the
oil level will be is to where the pushroll tube holes are in the intake manifold. This is #1 reason for adding a extra quart of oil to the motor. The weight of the oil also effects the return speed to the oil pan. Talk to you later. Rick L.
