TSP CNC LS6 vs Livernois CNC LS6 heads
I am trying to decide on some budget heads, and I'd like to hear some more info on these two. I have heard that the Livernois heads have a smaller runner which could make more torque, but they seem to be giving up some flow across the board.

What do you guys think?

Also, I have not seen many dyno #s or track times with the Livernois heads, so if anyone has them, post em up.

From what I can read about both heads, the TSP's will benefit a bigger cam (Int runner 235) and the Livernois will work better on a smaller cam.
PP also has medium size runners of 227 intake.

someone just recently put down over 440 to the wheels with a cam that was 228 to 232 duration...cant remember the split for sure.
the rear wheel torque was also over 400. this was on the tsp prc ls6 heads with competition valve job and stock valves. Car was full bolt ons and with no fast 90/90. it was an ls6 intake car.
although a bigger duration cam may work better...they will make good power with smaller cams as well.
I will have my numbers up in june, I am hoping for some good results.

I have Livernois Stage 1 LS6 heads, a 224/228 114 cam, LG Motorsports Longtube Headers, Offroad X-Pipe, and Stock Z06 catback and I made 420 RWHP/ 390 RWTQ. Last year I had their Stage 1 LS1 heads with the same combo and ran a best of 12.3@119.9mph with a 2.3 60ft. I should have new track times shortly.

The Livernois heads at first glance look very applealing with the cfm's over 300 @ .600 with a notable smaller port vol. 220 -vs- TSP @ 235. How did Livernois get thoses flow numbers so close to TSP without increasing the port volume to TSP's volume?
From what I read its the same 243 GM cast head, correct? So is Livernois just using smoke and mirrors with their flow rate or is there something else going on?

I'm a little bias but i like the TSP heads because TSP customer service was great, price was right and they perform. So i'm 100% happy with the heads from the fist call to TSP to the dyno results. If these heads fit the combo you want they are great.

Bigger runner doesn't mean **** guys, the CNC programs at the 2 companies are different.
BTW FYI, Livernois ranked 3rd at the JEGS motor shootout (with a ford block) but that shows that they know their stuff.
I run PRC Stage 2.5 heads and i'm very please with the product.

It would seem based much on the thread by Patrick G and the torque cam, which has a lot of info other than that cam. The port volume would play an important part of the power under the curve. If the TSP head has soft torque figures in comparison it to AFR 205 or AFR 225 for that matter and the flow rates @ .600 are about the same wouldn’t it point back directly with runner volumes?
If the problem with the ARF 205 is it starts backing up flow at higher lifts but is great in the torque area, and the TSP head is strong the HP area but requires a large cam and is soft in the torque area. The Livernois head seems to be the exact or perfect fit for max HP & Torque & Streetability. Then you look at the cost of Livernois setup, it sure looks at first glance to be far and away the superior setup.
The TSP also looks like it would really require the Fast 90 intake to really get full advantage, but the Livernois would probably be a better choice when running the LS6 intake, right or wrong?

Livernois heads are actually 227cc +/-. They increase the runner volume 15cc over stock (direct info from their head porter).

It depends on what you want to do and where you want to make power.
If you're like 90% of the people on here you'll get the bug and want to go faster. I've got an ls6 intake on my car, will probably go with the fast if they ever decide to make them not so hard on the wallet.
I think the PRC heads have more power potential in them if you want to go faster at the track...and step up to a larger cam, larger intake and a higher stall speed convertor or a tough clutch.
I can understand where Patrck G is coming from with his torque craze, which is great for the 6 speeds and lower stall speed street cars... but with a high stall speed auto you don't really spend much time below 3500 rpm's because the convertor gets past the lowend so fast.

What do you guys consider to be a "big" cam? I plan on putting either the new F14 in or the TSP torquer V2, which heads will complement a cam around the size of those two the best?
