I just bought a 2006 CTS-V ls2 with 140k miles and was only going to install long tube headers but when I went to install the headers I found broken exhaust manifold bolts broke off in the head so now the heads need to come off. I figure might as well do a head/cam swap. What heads /cam package would You buy for this Car?

 

I have run TFS, Cartek and TSP heads and for the money TSP heads cam packages cant be beat. Recently did 05 Ls2 vette 6spd, TSP stg 2.5 243's, 233/239 cam and headers, car put down 472/415

 

MMS 235s,FAST 102, Cam Motion ~ 231*/235* .620"/.600" 115*+3*
Car will still drive like a Caddy and make Big Power ~ 500 RWHP
With a Manual.

 

I don't like what I've read out of the tsp stuff, seems like they are down on power compared to all the others. That mast setup would be badass but is a bit out of my price range. I like 500hp that drives like a caddy haha

 

As I said for the money. Money is the only limit there is to making power. Mast, MMS, TFS, AFR and all the porters that have their own version of these heads are all pricey for what little extra power you get for the money. I'm almost positive ported 243's were the first heads to crack 500whp on a ls1 but thats hand ported and costly to. For most of here budget is the major factor and its hard to beat the tsp setup.

If it matters my current heads are TFS245's so I'm not just nut swinging here.

 

I hear ya. TSP is not out of the question just sharing results Ive read. Their 227 head looks promising

 

Im about to run a prc225 head and custom cam from tsp. Can't talk about performance and numbers yet, but customer service has been nothing but amazing. They got me a discounted package deal, responded quickly, amd answered all my stupid questions...
Customer service was top notch, and they have my business forever

 

Send current heads to Frankenstein. I also like the MAST heads...in your case maybe 245cc LS1 style.

 

 

Send those heads to AI for their full port work, get them to spec you a cam while they're at it...FAST 102/102.

 

If you are looking to purchase new castings, but don't want to get too crazy on spending look at the PRC As-Cast 225s or the TFS As-Cast 220s both are great choices and will yield nice results. As for what camshaft you go with there are many options available, and it will come down to what you plan to use the car for the most.

 

Idealy, I would love to get a ported LS3 intake and GM Performance CNC ported LS3 head package for my LS2 GTO.

 

I'm leaning towards the btr tfs as cast 220's and their stage 3 n/a cam. $2100 for the heads

 

We have killer pricing on CNC porting the heads you currently have,
Starting @ $750.00, That will include the following:
CNC port intake runners
CNC port exhaust runners
Surface heads
Face intake surface and exhaust surface
True valve cover rail

Logo heads
Assemble heads

what do You guys think about ls3 heads and intake with a custom cam?

 

I think this will be the combo that'll kick ***!!

 

I think these heads and maybe the stage 2 cam instead since it's a 4000 lb car.

 

Honestly I would go for a custom grind by Pat G or Brian Tooley

 

I asked the guy I've been emailing From Btr about a custom cam He said it isn't needed?

 

With all the available cams out there for the LS motors, with their various lobes, specs, etc...a custom grind really isn't needed IMO. I mean it certainly won't hurt, but it probably would end up being something very similar to one of the off the shelf grinds anyways lol
