I recently discovered I have a bad lifter on cylinder 5 exhaust. The lifter is pretty concave, enough to hold a few drops of oil if put on the surface. So now I'm going to replace the cam and lifters and was seeing if anyone has some input on what to run with my current setup. The cam I'm running now is the Comp Cams Magnum 292H. 244/244 duration and .501 lift. I've been running it for a few years and thought there may be some new cams out that would give me better performace. Heres a run down of my setup.

78 chevy 350 block (standard block, not bored out)
9.72:1 compression
1.5 Harland Sharp roller rockers
Dart Pro-1 Aluminum Heads Part#11321111. 2.02/160 valves, 64cc
Dual plane air gap style manifold

This is in my 88 IROCZ with a 700R4 with 3500 lock-up stall and 4.11 posi trac rearend. Car has full interior and is a street car. Weekend and nice weather cruiser. I'm looking for suggestions on staying hydraulic and maybe going roller.
