Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION

LD340 or Perfomer airgap (listed in post)
W2's or IMMs (my mistake ... they are Indy's) ported to flow in the 270 range @ .550 intake ...195 exhaust (listed in post)
I would consider any recommendations on heads...
leaning away from the W2's because of expense although I have run them before with fantastic results...
