ETP 215's VS TSP PRC 200cc Terminator Heads or others for a 346 Yeah I have a 02 z06 with a ms3 cam, long tubes, ud pulley, air intake, catback, tune. I want to stay n/a. So I hear that ET makes some of the best heads out there but I was wondering if there would be any difference in numbers between the ET 215's and the texas speed prc 200cc terminator heads? Which would be better to go with? I am trying to get over 500 to the wheels so keep that in mind. Also, I am not conscerned about $$, I just want the best possible hp/tq. Thanks guys.

Beast, since he has a 346 wouldn't it make more sense for him to go with the ETP 215?
The ETP 225 flow numbers on a 3.900 bore are the same as a ETP 215 on a 3.900 bore.

What heads produce the best hp for a ls6 motor? Yeah I am trying to figure what heads are best for my 02 z06, thus far I have kooks long tubes, varam intake, ms3 cam, borla stingers catback,underdrive pulley, tune. I want to get over 500 to the wheels all n/a. What would be the best heads to go with? $$ doesnt matter, I just want the best numbers.

I too am interested in how much power you make now, I know how much you can gain with the TFS heads and Fast intake, give me a call and let me take a shot at making the power you want.

Going with the ETP's will allow you to run higher compression without flycutting....I think as much as 12.5:1, but when C/R goes up it "usually" requires more octane or less timing.....
If money is no object I suggest the ETP with Jesel rocker arm setup, and you're gonna need the full assortment of bolt-ons including an EWP, and a fully ported Fast/TB(speak with Tony Mamo of AFR).......
Good luck!

Why dont you go with a already proven setup like TTP or Cartek. Both of these shops have cars in the 500RWHP range. Cartek has been building some of the fastest cars for many years now.
