question about vt stage 2 cams

[i8ur-riceburner]

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 comp springs if you already have them in your heads...but if you don't have them yet i'd go with the Manley springs.
