My Power Disk Brakes are frustrating me...

I second the Rhoades lifters. I picked up a set for SB for $25 on ebay, but you don't see them often. I recall the same ones fit a BB too. Besides better idle, it should give better mileage and lower emissions. You live in the LA Basin, and many there now enjoy breathing clean air and seeing the mountains from the beach. No need to have a crappy running car.
