Default LS7 Heads????

Is anyone using the LS7 heads in their C5? I thought that I read ealier that there were some problems with the tuning with these heads. I see where some of the tuners are getting 550 plus rwhp on the C Z06s
and thought they might be nice on a C5R block or would it be better to use the AFR 225s?

Thanks

Seems like the current choice appears to be L92 heads w/L76 intake manifold combo instead. Just gotta have 4" or larger bore.

Now, I'm a big AFR guy, but I would lean more towards the hand ported LS7 heads, with the oem intake matched. I like to keep it simple, and I prefer the LS7 intake, though the L92's will come on strong shortly, with better intake choices for them.
