A friend of mine just put a set on his T/A this past weekend. He is going to the dyno this coming weekend. The heads look great. Should be around 450rwhp with his G5X3.

They don't release the specs on it. It's a descent amount bigger than yours though. I have seen people say it's 234/242 .600/.610 I don't know if that's correct but I'd say it's close.

I dont really hear to much about there heads on the board. I find it kind of odd because they flow well and have a decent price. Do they just not make power? Do they not advertise. Hell, they won the engine masters challange so they know how to make power.

I have a set of Livernois Ported LS1 heads on my car and will be switching the the LS6's very shortly. With those heads, a 224/228 114 cam, longtubes, and offroad x-pipe I picked up slightly over 100 RWHP. Stock I ran consistent 13.4's @ 104 and my best after the mods listed above was 12.3 @ 119 mph. I couldn't be happier!

I had them do a set of LS6 heads for me, fully CNC's aand assembeld with all of my parts to my specs. They did a very nice job and were a great group to work with. Very customer service oriented. I dont live to far from the shop so it was nice to walk in and browse their showroom, awesome to say the least. I highly recommend them.

There is a guy on corvetteforum.com with a Z06 and he added Livernois heads, a 222/224 575/575 114 cam, and longtubes and picked up 80 RWHP and 50 RWTQ.

Going from 300 to 400rwhp is easy. Going from 400 to 500rwhp N/A
gets costly. The good news is that these heads are a steal.

You should gain anywhere from 30-60rwhp from a good set of heads and tune.

Well, they were only released on Dec 14, so they have been available to buy for less than two months. Plus it is the middle of winter. I wouldn't count them out just because you are not hearing any hype. Livernois is a proven race shop and I am sure their heads will work as advertised.
