Rattling is all gone... I jacked up the car today tightened the arp converter bolts and ripped the dust shield off. Started her up and drove for 5 minutes in the neighborhood. Couldnt get rowdy because I had my 2 year old in the seat next to me.
Shifts smooth as butter, a little early on the 1-2 shift but I havent fully adjuated the kd linkage yet.
I also changed the oil and added a zinc additive. The other oil was used as break in oil for the new heads and had a bit of a gas smell due to it not starting the other day.
