Yep they should have washers under the heads. Not a normal washer. Outside diameter is smaller. Did you get a new balancer or have that one reconditioned? There is a place that reconditions them. Almost the cost of a new one. As also I recommend getting a starter motor off a ram pickup, ram van, or dakota with a magnum V8 or V6 it's a mini Denso hi torque. It's small, weighs only about 8 lbs and has more power than your stock starter. I get em used from the junkyard for about $20. It's a direct bolt on.
