I am going to be doing a cam in my 04 GTO and starting looking at some of the "budget" heads that are out there. I am 95% sure I am going to go with the Comp Cams 54-428-11 228/230 .571/.573 cam. By the time you buy spring package its not a whole lot more for a set of ported ls6 heads. which set of heads do you reccomend. Looked at the Patriot stage II heads.


Mods to car are:
CAI
Kooks 1 7/8" LT's w/cats
Underdrive pulley
3.91 gears
spec stage 3

 

5.3L Stage 2 (2.02/1.57) CNC ported.

 

The ported 243 heads seem to work quite well. The thing I don't care for on many of them is that they are just hogged out, and the material gets a bit thin.

For the money, I like the Dart 205 heads. A bit more than the ported 243 heads, but they work just as well with a small intake port. Plus, there's material in stock for porting if you want to.

 

5.3L Stage 2 (2.02/1.57) CNC ported. have these heads also. tsp has a good deal on them

 

These the ones your talking about?

TSP LS6 Stage 1s. I'm running the Torquer V2 (232/234@112)with them and had a best time of 12.01 so far.

 

For the money, go with the L92 heads with a spring upgrade good to .650 lift from SDPC. Their website is www.SDPC2000.com. They outflow MANY of the heads out there and are around $1200 or so.
You can get the L76 intake with TB, injectors and rails for about $500 more.

EDIT: I saw your were stock cubes, not sure how that would work out for you. If it is a 402 you should be set though.

 

i read in gmhtp the you need a 4" bore to use the l92's. i could be wrong, but i think that's what i remember reading.

 

I've got some Dart 205 or 225cc heads in stock for steal! Anyone interested can PM me for pricing.

Also, as mentioned above our upgraded L92 heads are a very popular choice
