Hey Terry

That price is on the 243 LS6 casting head? I just want to make sure I got that right . Thats a killer price if they are a real ls6 head 243 casting .

bodhi

Terry told me that they buy everyting in bulk from GM. They should be real 243 castings. He told me that they purchased some obscene number like 300 sets.

If they are defintly 243 castings I know a few people that would be interested.

TVWilkes

We bought the castings from GM.They are raw not machined.Since they were raw they will have no casting number on them.They will have our own number on them.You can get the heads with machined chamber ranging from 60cc to 75 cc.The heads are not milled,they are at the factory deck height.The smaller chambers are shaped like the #243 casting.The larger will be like the #317 or #035.thanks,

No offense ment here Terry but when you say "chambers shaped like the #243 castings" kinda tells me they are not the REAL LS6 243 castings.Im sure they will flow like a ***** but atleast if they are lq9 or lq4 heads please dont try and pass them off as anything else because they are not worth as much. It doesnt seem like honest business practice even if they are very simular. But im not with the Better business bureau so who cares what I say. I thought there was another post where you said they were lq9 heads. Maby im reading it wrong but just seems fishy . Good luck with them Im sure you will sell tons of them.

The heads are raw castings LQ9 from GM.The chambers will be cnc machined so they are the shape of a ported LS6 head.The smallest chamber will be 60 cc.The deck is not milled to achieve the small chamber.As I stated above this is our own LS6 stlye head.It will have our number on the head.

bodhi

So essentially it IS the same as the LS6? Are there ANY differences other than the casting #? Will the chambers be the same volume and design as the LS6? What about port volume?

TVWilkes

The port volume of the heads are 223 cc.Yes,essentially it is the same as the LS6.

TVWilkes posted in another thread a few days ago
and TVWilkes posted this more recently

First, off I'd don't there is anything fishy, Terry is being open with what he's doing because he told us in the first post made several days ago.

The terminology mustbe specific and accurate or it will lead to misunderstandings. The second statement clearly calls them LS6 heads not reworked LS6 heads. In my mind that's the same difference in a "real SS Camaro" and a replicia "SS Camaro" - funtionally the same but actually not the same.

I think I would call these "LS6" heads something like:

Patriot LQ9 heads CNC'd to LS6 specifications

Patriot LQ9 heads CNC'd to ported LS6 specifications

Patriot heads machined to LS6 spec

Patriot heads machined to ported LS6 spec

Patriot castings machined to LS6 spec

and so on...

If someone purchased thinking they are getting "real" LS6 heads and got head that didn't have the LS6 part number on it, they make a real stink out of it...

TVWilkes

That is right,Patriot heads machined to ported LS6 spec.As I stated before this is basically an aftermarket head.It will have a patriot casting number on it.thanks,

One final question - if it was you buying a Stage II head, and 1800.00 was your limit. Which head would you purchase? BTW, thanks everyone so far for all your input. These boards are VERY helpful - almost to the point of being confusing with so many people suggesting this or that. I have been peeking at everyones sig. for ideas - and see some interesting things.........

This guy is great. It's great to see a vendor back up his claims and monitor the marketing of his product. Commitment=Excellence. This is a no brainer in my .02

Not being an expert on the subject I have to say I'll take CNC vs Hand porting every time. From my understanding hand porting a set of heads is time consuming and also very hard to duplicate or shall I say REPETE. Although I am a little bias on the matter since I have a set of heads on my car that have been CNC'd. I am making that magical 400# through a TH400 and a 12-bolt w/4.10's. I also agree that money talks and walks so it is well understood that if I could spend 1500 and see 25hp compared to 2500 for 35hp it's pretty much of a no brainer on what to do(1500). Also LS6 heads haven't proven enough to me to merit the extra dough...

I wasn`t really upset for the cost of my S2 heads at MTI. They put my whole set-up together and I love it. Got over 400rwhp with A4 ,12-bolt and all. My race weight is 3800lbs with me, alittle heavy! MTI Rocks! Enough said!

Mad Max,

Stage 2 and $1800 the limit, if it were me...I'd wait and see how a few of the Patriot cars dyno with the current heads. If they do well, I'd call up Terry and ask a bunch of questions about the LQ9's machined to ported LS6 spec's because they sound promising

Like...

Flow with and without a LS6 intake in place.

Flow with and without a 1-3/4 diameter 6 inch exhaust pipe in place.

Reverision?

Swirll?

What lift the port stalls at with and without intake.

Details about the valve job, 5 angle, 3 angle, radiused etc

Which springs

Could I pay a few dollars more for bronze valve guides.

Would he suggest a dished exhaust valve to up exhaust flow a tad etc

Can I get them milled to such and such to get a specific compression etc...

If everything checked out I'd be very tempted to be the first to try the Pat LQ9/LS6 head.

Good Luck

Mad Max

You guys are killin me! Actually I am looking into 2 options. BTW, I feel the same way - 25 HP for 1500.00 vs 35-40 for 2500 - no brainer. I am looking to heads and a (milder) cam for emission reasons - otherwise I would just go for the GIANT cam.
BTW, anyone on the boards using the AMS Vortec 4800 heads/cam combo? What do those heads run? I saw some good numbers a few issues back in a issue of GM High-tech.
As for deals - I am in no hurry, as I will probably buy a part at a time until I have everything and then do it all at once. That way I can get it tuned after too.

TVWilkes

99 Black Bird T/A,I will answer any questions ask.The bronze guides are standard equipment on all of our stage 2 heads ( LS1/LS6/LQ9 ).Yes,any of the heads can be milled what ever someone desires at no extra charge.
