Critique this custom cam- turbo 6.0
Guys, I am picking out a cam for this motor and was given the spec below for a custom grind. I wont share the vendor's name for now so you can judge just off the specs. I am looking for some advice from those more knowledgable than myself since this is my first turbo motor. This is mainly a fun street setup that will rarely make it to the track, going in a 70' Nova with a TH400. I want a mild cam that has a wide powerband, decent idle, and will be easy on the springs and the rest of the valvetrain. I wont be going past 6500rpm.
Motor:
6.0l LQ4
LSA heads with the "wings" removed (should flow very similar to an LS3 head)
LS3 intake
TC76mm turbo, going to keep it aroud 10lbs for as long as I can resist
The cam specs I was given are:
219/222@.050, 607/602, 116lsa.
This was more lift than I was expecting, but again I am not knowledgeable enough to know for sure.
Originally I was considering an 02-04 Z06 cam (204/218, .551/.547, 117.5lsa) and the Lingenfelter GT2-3 cam (207/220, .571/.578, 118.5lsa) but I was going to bite the bullet and just get a custom grind right off the bat.
Whic one of these is going to be the best choice for me and why?

219/222@.050, 607/602, 116lsa., FYI you could just substitute the 219lsl lobes for 218lxl lobes
That looks a 219(lsl) and 222(lxl) lobes. The lsl lobes are aggressive, but the lxl lobes are not. Don't let the lift scare you off, it's the ramp rates of the lobes that'll take a toll on your valve springs.
IMO, this would be a good choice.
218/218 115lsa +2, lift is .598" with LXL lobes, and it has -12*OL.

I need to figure out what kind of springs to run. The Comp dual spring kit that was reccomended is $500 with tool steel retainers, which is hard to swallow. Originally I was thinking PAC duals but I will have to read up on the choices after I get that cam ordered.
