Well... I can answer some Tech questions but because I'm a outsider (non-sponsor) I can't help with price checks...

As for the LS6 vs 215 heads... I'd venture about 40-45 RWHP with a good tuner. Even more with a top shelf guy (A&A)....

my z06 is completely stock. so if I add these heads, 40rwhp minimum, no other changes?

What do you think of a cam setup for the 215s with a lsa of around 117, agressive ramps and moderate duration @ 0.050. Something like
214/224/ commensurate w/air flow lift of heads(600??), 117 or so lsa like stock. i could be wrong, but it appears these ls6 engines don't need overlap on the cam with a stock exhaust.

ETP produces some of the most respected CNC'd heads in the industry and their new cylinder heads are setting benchmark flow numbers.

We will have a set or two in the next few weeks (depends on ETP's back order status) and publish our independent dyno results.

I could probably get 370rwhp with stock heads and tuning. Have seen 364 already. Thats only 28rwhp off your FULLY MODDED ETP HEADED, LONG TUBED, COMP CAMS (ED CURTIS) engine. What am I missing?

Thats great, except someone is blabbing about 40rwhp gains++. You gonna back those claims or is this BS???

Whoa dude... WTF is it with the attitude?

You asked, and I gave you "my opinion" based on the delta between the cylinder heads and potential HP increases when the combination is maximized. If you don't agree fine but cripe, lighten up!

Don't bother looking for an answer to your cam ideas either. I'm done giving out any more info for free. Try Google.

We will post our results. I don't no about blabbing but I do know that the potential exists and my advice is to wait for the dyno and track times before arguing otherwise.

If those numbers are real out of the box and untouched. That's really good especiall on a 4.000" bore.

Like Charlie said. Let's see the dyno results.

I say, let's see the track numbers to follow.

Amazing stuff coming to market.

Ok, fair enough, but 45++rwhp??????????? Thats a bit optimistic. If those heads add that much hp by ONLY adding heads, I'm buying at almost any cost. Keep in mind, I'm at 550 lift and anything beyond is useless. As for cams, like many custom grinders, I usually call COMPETITION CAMS directly for a lobe of choice using the following data below.

blktie, strange thing. Cartek researched the very same cam you have years ago and it works great. I once used the 3722/3724 (224/228) and it worked well also. Looks like you chose a good cam.
