I can get a set of ls6 heads for a good price. would it be worth it to have them installed they are stock ls6 heads. How much would a full bolt on car with a tr227 benifit or should I just keep my stock heads.

z06 intake, Hooker LTs, FTRA, ...

Since you have the LS6 intake and a bigger cam you should benfit a good amount. If you get them fairly inexpensive I'd think they'd be worth 20+rwhp or more. I'd have them flowed B4 you bolted them on though. Just so you know how much CFM you'll be picking up over the stock LS1 heads.

I've asked Speed Inc. the same question and they told me that you would benefit about +15hp over LS1 heads. Not worth it if you have to pay a lot for them. If they are fairly new you could probably sell them for a good buck and offset the cost to pay to have your LS1's Ported and Polished <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> They usually go for about $1k it seems in the For Sale section.
