Thanks for the input guys, I know there are probably a few bottom feeders out there that would try to scam me on that offer, but I stand by it! Of course, first you have to come here and watch us flow 5 sets and get the exact same number! The bottom line is,If somebody buys any of our heads, and isn't happy with them, then we'll do whatever we have to to make you happy.

Think about it,look how much I have to lose by posting false numbers, or lying to you guys.
Knowing that, my willingness to post numbers, and make bold offers, should tell you that LPE products will do what we say they will.

I understand the differences in benches(I used to work in the portroom here!), but a good port will flow good on any bench, without fail!

We could flow the LS6 heads with intakes, and pipes on the exhaust, but it would be pointless, since no other numbers anybody is looking at have been achieved that way.

We do have a stage 4 LS6, but I'm still taking heat for the stage 3 numbers!!

If anybody is holding off buying heads untill they know all of the numbers available, call me or Josh and we can talk .

I want to compile a similar list of flow numbers with the LS6 intake on and 6 inch pipe on exhaust.

This would give us another way to compare.

While I know there are limits to what flow data can tell us, I think the best way to look at flow data is with the intake on & pipe on exhaust. This seems more meaningful than a bare head being flowed. GM feels that way too so there must be something to that. I know that's not the traditional way it's done, but that doesn't mean we should limit ourselves to just looking at data in the traditional way. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I do have data to compare additional flow numbers with LS6 intake & 6 inch pipe in place too! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

BTW, I'm looking forward to you next installment of flow data for your chart.

While I would be delighted to have a set of your LS6 heads, but I'm out of the market for heads for a while. My car is getting TEA 5.3's & cam installed tomorrow.

However, my long term goal is to build another engine for the car. It will either be an LS6 type clone or stroker or all bore. So I'm always asking questions and learning for the next engine. For my next engine LPE, TEA & SRP are the contenders for doing it's heads. I have referred a friend to this thread that's thinking about heads & cam, as I think the LPE heads are quality & performance at a competive price.

Ed,

Thnaks for coming out and posting the new flow numbers on your St II and St III heads. I do agree your price is very competetive on the Stage I's especially.

I think folks may be confused a bit about some statements that were made in an earlier thread. I am going to state my understanding. If there is anything that is not correct, please chimein.

The LS6 CNC head was designed with input from GM and SCCA. The program that is used was designed around a stock valve. The flow numbers that were specified were with an intake manifold and a 6" stack pipe on the exhaust. Those numbers have not been posted, not that they are hidden, but they would be fairly meaningless unless you have something to compare them too.

Heads are normally flowed bare. Sometimes shops use a pipe on the exhaust to help out the exhaust runner flow numbers.

I am sure that Ed and the folks can flow with an intake and a pipe, but unless some other shops did the same, it wouldn't mean anything. Also Ed while I respect LPE's willingness to stand behind their heads I would also caution your statement about offering money + 10% if they don't flow.

I am sure there is someone out there who would go find a shop with a garbage bench and go around posting some skewed numbers looking for a free lunch, or just to be a jerk.

In looking at your heads they appear to top out @ 314 @.500 at .600 they are still there. Do they go turbulent at some point? If so, what is that number?

Also, is this the best numbers y'all can get with LS6 heads. I know you could cut and reweld heads and get crazy numbers, but i was wondering if there is anything above your stage III.

Also, do any of your heads carry bigger valves?

Thanks for your participation.

Whoops just saw your post in the other thread which explains that y'all only flow the CNC heads with an intake and a pipe per GM instructions.

So, y'all have a stage IV head. Can you elaborate on its performance...

WOW ED those heads are a pretty goood bang for the buck.

I think your S1 heads are $100 less that TEA and flow the same or more. Can anybody verify this?

My question is in regards to a H/C package from you guys. I was thinking for a while to build an extremely fast car with a TA or a ZO6 but the aftermarket is a bit on the pricey side and is understandable but which ever I buy I am definitely in for improving performance over stock.

My question is with your S1 heads do you have cam that complements it nicely but retains a "sleeper" sound with nice daily driven manners on either car. I would call you directly but I am sure there are a lot of other people who might be curious about H/C package like this.

In your opinion ,and I stress opinion, whats the maximum avg Hp/Tq between 2k-6k that could be achieved with the above given constraints?

Thanks again for posting your flow numbers and coming on to the boards even when you have to put up with jerks.

Ed,

Thanks for coming in here and being professional.

Anyways, what kind of flow numbers are the $1600 LS1 heads on your site making?

That seems to be the area where you can sell the most product here.

Thanks for the compliments guys, I'll get you some numbers on the LS1 heads, and some suggested cam specs to run with them & the LS6 heads.

I think the best way to get good HP/TQ numbers on a stock f-body for 2-6K is a good head & cam package with LS6 intake, backed up by long tube headers, good cat back exhaust system, good cold air intake,and a better rear gear. A4 cars would benefit from a better converter. The most important thing is proper ECM tuning! Some guys will tell you that you don't need tuning, and the car will run, but it will pop & fart & stumble, and idle bad, and set codes. I know some guys don't care about that, they just want real aggressive cams that give them max ET's, and that's fine for them. They can run the same package with a bigger cam. When we sell a H&C package, we also offer you ECM tuning for $475.00, that is money well spent toward future happiness. I know most of you guys already have the good bolt on stuff, so for about $2500.00, you could get heads,cam & tuning that will give you really goood results!

I'll post some LS1 numbers later today, and remember, all of our package prices are the same, no matter what casting you choose.
