98 dakota---needs a short block--found a low milage from a 91----figured to change the heads out--found the 98 uses the stretch head bolts and the 91 has standard LA headbolts--and there are different threads to those bolts----looks like i can put on the new heads on with the old headbolts-----any other quirks going to show up with the timing cover/waterpump? yeah i know the damper and pullys are different---thanks bob
