They are quite a bit better than LS6 heads. The best ported LS6 heads I have seen were in the 330 CFM range. I read that the C5R heads ARE was using on their 8 second monster flowed in the 370CFM range.

Yes, C5R heads are definately better, however I'm not sure if it is worth all the trouble unless the car is an all-out race car. Don't you have to have custom headers made as well? And if anyone would slap a LS6 intake on C5R heads, they should be slapped, even if it did fit.
But, if you can get them complete for a killer price, say with titanium valves and all, I'd go for it.

Hmmm I didn't know about the intake and header issues. It doesn't look like it's good for my setup afterall. Damn I was all pumped up to get these too.

A fully prepped set of C-5R heads with custom intake is about $10,000.I was going to get them for my track car but passed due to the high cost.They're bad *** but have an equally bad-*** price.They are best left to someone that wants to set a LS1 record and does'nt care about cost.

Headers are not an issue with C5R heads but it is true that an LS6 intake will not work with them.
C5R heads are WAAAAAAAY overkill for a street engine. Tinsy tiny combustion chambers spell HIGH compression ratios. They can flow ~400 CFM when ported properly.
