spec's of a cam i've been told to use

lunati solid cam 40317
552 in / 570 ex lift
254 in / 264 ex @ .050 duration
108 centerline
18/20 valve lash
what do you guys think ?
my Indy springs are good for .600 , with my 1.6 ratio rockers that will take the exhaust lift over .600 but the valve lash will bring it back down to .587 .
i don't really like the 108 lobe sep but oh well . we are also thinking of nitrous ( 150 - 200 shot ) that's why the extra ex lift & timing . what do you guys think .

It sounds like a nitrous cam with the extra lift and duration on the exhaust.
Is that one of those "street rollers" or is it a solid flat tappet?
