Terry
You are looking for every bit of power you can get, I believe? With the intake on the ls6 heads flow a little better from 600" on up. Without intake they do much better. We need a better intake. Big news, right.

<hr /></blockquote>I'm going to use a ported LS6 intake for now, but I'm building this thing for a good sheet metal intake. I'm sure some will be out soon.

Re: Best price on LS6 cores?

The springs in my current heads are 941s and they have never broken. I think they are magical. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

So Max I'm finally going to have a set of "special" heads/cam in my car, just like the Cartek cars! I wonder if I'll pick up over my off the shelf MMS parts? I'm shooting for another 25-30rwhp from 5500-7400rpm. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Best price on LS6 cores?

though I think a number of interesting topics have been ruined by the "devils" advocate approach Terry, this is hard to say, I don't see an inconsistancy here. I would not spend money for ls6 heads, unless my cam was .600+ or a better flowing intake was available. LS6 heads without intake flow better from .500" and up. Good luck with that lift. You should have a lot of torque up high. I hope it holds together. Can't wait to see your charts?

It's over that that counts...

<hr /></blockquote>There is going to be nothing "off the shelf" with the new setup. I'm doing exactly what Cartek does, building a one off high performance setup. I'm only doing the intake valves, which will be in the $600 price range. When its all said and done the complete set of heads is going to cost less than the Cartek heads with much better parts. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Just to clarify son-of-Julio, Terry's current heads are like $1800 Stage 2 5.3L heads with NON-titanium 2.02/1.57 valves and 941's.

Good luck to you terry. Now how are you gonna fit 2.1" intake valves in?

Re: Best price on LS6 cores?

After months of arguing that LS6 heads are a waste of $, you finally give in. I guess all of your arguments in the past were BS. Are you going to use a set of MMS springs?

I found out what MMS stands for:

Mediocre
Made
Springs

I argue for fun. I don't always take the side I believe in, its good law practice. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

RE: the LS6 heads my belief is for lifts > .600 and/or rwhp > 475 I think they are a good choice.

RE: MMS' springs, they will sell you whatever springs you'd like.
