I've found some SAE 30 in stock at a local Napa. Temps are warming up enough here I could probably get away with a straight weight oil for the next few months. Using Quaker State Defy 10W30 and a Mobile 1 filter presently. The QS oil had a pretty high ZDDP content, was cheap and readily available. Did the break-in with Shell Rotella 10W30 and the Lunati break-in additive. Rotella was another one recommended throughout several forums as suitable for flat tappet cams. I love my Amsoil, but at over $10 a quart for their high ZDDP content oil, Valvoline is looking pretty good.
