might be doing cam swap, help decide.....

[swb85]

Pretty sure I have a collapsed lifter, haven't torn it down to verify yet. If it is, I'll probably go ahead and do a cam/lifter swap since I don't know any of the current cam's specs (PO installed it). Thinking about these cams:

Comp 268H: 218/218 .454/.454 110lsa (1500-5500 rpm)
Comp 265DEH: 211/221 .42/.465 110lsa (1500-5750 rpm)
Comp 275DEH: 219/229 .452/.482 110lsa (2000-6000rpm)
Comp XE268H: 224/230 .477/.480 110lsa (1800-5800 rpm)

Motor is a 355 with stock iron heads (mildly ported according to PO), I assume 76cc chambers?(no clue here), performer rpm intake, edel 1405 carb, longtubes/2.5" duals, muncie 4 speed, 3.42 rear gears. No idea on bottom end or pistons. The current cam is aftermarket, has a tiny chop to it at idle, so I think my current valve springs are probably ok (only 12k miles).....would like replacement cam to have close to same overlap, maybe a hair more. Not gonna say no to a bumpin' idle. Anybody have any input? Other recommendations? The 224/230 is probably as big as I'd go.
