Hello Andy,
I would assume Jeff @ Modern would give you some set-up tips if it's not too late. It's been a while since I had my -1's done locally for the paired T&D rockers but, the set-up looks similar. One suggestion I will make is to machine the head for a helicoil or timecert for the rocker holddowns while your at the correct hole centers. Also by the time you get the pedistals machined down to the correct height the holddown bolts MAY be too long and bottom out...so check that as well. Another thing I will throw out there is a suggestion made by 340King from another Mopar site. He recommended to machine the pedestal tops on a perpidicular plane splitting the loading angles of the pushrod and the valve. I hope that makes sense to you.
