What heads for the LS7??
WCCH ports LS7 heads as well. They aren't cheap but they look awesome.
Mine are from Richard at WCCH and flow 360 intake and 252 exhaust. He basically only touches up the exhaust side and leaves the intake alone. 1.46" diameter springs installed as well rated at .700" lift.
Go with the ported LS7 intake as it won't hit a wall in terms of flow above 6800rpm. It pulls way up there as tested by Katech and others.

You'd probably hear much of the same stuff from a former fourm member, but
1) he's really busy now sculpting in aluminum
2) he's banned
I think 1) takes precedence.

Most head porters don't build engines. If their ports work we know because of how the engines with their heads perform, either on the dyno, the street or the track.
If you want to buy "head flow" that is your option. If you want to buy "cam specs" that, too is your option. I really don't know what kind of head and cam specs LG provides to customers. I was just using them (a sponsor) as an example of what is working, and what other folks may try to equal or exceed. Use LG's stuff as a benchmark. When someone else equals or exceeds the performance on the dyno/street/track, you then have other viable options.
If I, personally, were buying such a package and the seller was installing it, I just want to know how it performs and drives. If I were installing it myself I'd want to know the ICL where I should degree in the cam. Anything else is just hype so I can say my heads flow XXX CFM and I have a bigger cam than someone else. If my car is faster, that's what talks to me.
Again, personally, even if I knew the "magic numbers" of what I bought, and my car was fast, I'd lie thru my teeth about those "magic numbers" (flow, durations, lifts, LSA, advance) to mislead my adversaries.
Head flow in CFM (quantity) really isn't the be all and end all of porting. Even if you have the numbers, do you think you can predict how one combination will perform compared to others? If "yes" then you should buy by the numbers.
I'm not saying you are wrong, RC45. You probably wouldn't be a customer of a seller who didn't tell all. You vote with your wallet (or credit card). That's what's great about a free market.
FWIW, I don't have any connecton with LG, nor have I ever talked with them. I just watch and listen. Sometimes(?) I hear more bovine scat than I hear honest, useful information.
Just my take on how all this stuff works.

Strange how when any one of you folks buys your new sports car, you want to know every spec and expect to be told what to expect.
Yet - suddenly, by some miracle when you want your cars modded, you are expected to take people on "their word"
and if you ask for specs youare ridiculed and chastised.I never implied I was buying "head flow" or in the market for "cam specs" - the questions were simple - What is the data for various components?
I simply asked my car builder to build me the baddest meanest muthatrucker for the wad of cash I handed him. I know it is going to be a demon everywhere, but that didn't stop me from asking him the specs of each component, and he never had a problem telling me.

It's probably a good thing you had a wad of cash. He saw you coming. It doesn't happen to be Barnum's Engines, does it?

They take very good care of him over there.
I have chosen another route, to attain the same result. I want 575+ RWHP. Will I get it? I don't know. But I trust that LG has done his homework and has provided me a good solution. I don't care about the flow numbers because I would always choose the highest flowing ones I could find, knowing it will hurt me.
RC45 on the other hand, is working together with a builder to meet his needs. And he knows what he is getting. I expect to see 575+ from his car in the next few days.
It's all fun. And their are different ways of getting there.

You got tired of the LS2 licking that a$$, so you built the LS7. I match you 200 more HP, and raise you 35.

I am done after this for awhile. I wonder if either one of us will hook it or not.

Like Jon said, it is your money, spend it like you want. MTI is a good shop, they will take care of you.
EDIT: I just don't get what your point is. I can understand wanting to know things, however me passing someone is more than enough knowledge for me. Do I know the specs on my engine?? yeah, I do. Will I ever tell them to anyone else?? Probably not. Why?? Because it doesn't really matter.
Like Jon said, if I am paying someone to do the work, then I will pick up a finished product that performs andthat will be enough forme. If I am installing the cam/heads/whatever myself, I would need to know a little more info. And if they didn't want to tell me, I can have the cam doctored and find out for myself.
I do not blame LG for being the way they are. They do not sell flow numbers and cam specs, they sell hp. Like Jon said, they seem to have a little of an advantage in the LS7 type stuff and they want to keep it. I just use LG as an example, they are not the only one's to keep their secrets.

I can't imagine running anything but the LS7 heads on the LS7 block. It allows you to use the LS7 intake manifold which is pretty damn good.

Agree on the LS7 intake but it only has so much HP in it. After that you are pretty much on your own. It looks like the '7 heads could make some REAL power if you can get the wind to them thru good runners. They may not respond to conventional wisdom as I mentioned. Talk to them real nice and they might tell you what they like. Don't try to tell them what to do.
