I talked to Kirk at Bullet Cams today and he recommends a Hydraulic roller as well.

296/302 advertised
242/248 @ .050
600/600 lift
110/108

w/ 130#-150# seat and 325-375# open spring pressures.

He said it should be good for right around 600hp and fairly streetable with a Vic Jr. intake and 3500 stall converter.

He also finally gave me a definate answer that the stock type lifters can handle up to 612 lift.
