question about vt stage 2 cams
 

i was thinking about buyin the vt stage 2's to put them on my stage 3 ported pi heads, with comp cams valve springs. now comp cams valve springs says its only good for cams up to .550 lift. the vt stage 2 cams are advertised for a lift of .560/.575, so does that mean i cant use comp cams valve springs? which ones could i use?

You can use the Comps, but they arent much better then stock. Instead Id use Crower or Manley Nexteks.
