goodwrench crate motor/ cam question

A buddy and I dropped a 350 in a 72 datsun 240z. The motor is a goodwrench crate motor #10066038 made in mexico. I runs like a rapped ape but it needs a little more cam. The motor has about 20,000 miles on it.

I bought the summit 1104 cam and lifter kit 224 intake 224 ex. @.050 and 465 in. and ex.

The motor is stock the way it came. Is this cam too much lift for the stock springs? Will it run good with the 8.5 compression?
I did read and read and some say anything under .480 will be fine while others say anything over .450 will cause bind.
thanks bob
