I'm pretty sure this is gonna start a debate, but I've got question or two about this cam. I'm curious if anyone has ran it with stock "new" 360 valve springs? good, bad? And is there an alternative to the recommended lunati springs that wont require any head work? Thanks

Don't do it.

I ran a set of mopar performance springs with my 10200704 Lunati cam. Not stock springs either mind you, but single springs with a damper that were recommended by the guy that did the port work on my heads. While stiffer than a set of OE springs, they weren't stiff enough. The result was a totally ruined set of Harland Sharp rockers.

Lunati cams run pretty fast ramps, and they need springs to suit that. I'm not saying there aren't other springs out there that will work, I'm sure there are and maybe someone can give you a working combination, but new 360 springs won't fit the bill.
