what heads do you have and what did you gain from just adding heads

 

Had 380 with cam only.

Heads and Cam went 420rwhp.

Ls1 241's .035 mill with stage 1½ portwork.

 

Just adding ported TSP LS6 heads gave me +25rwhp over stock also LS6 heads...no compression, valve, gasket or cam change.

 

Not to hi-jack your thread or anything, but what would the gains be on a FI car? Let's say LQ9, if any gain...? *newb*

 

On a 6.0 liter head? What size CID?

 

Im not in your bracket of big motors and high horsepower numbers, but I am pleased with this

Well you did

Post another thread

Anyone else that just added heads after a cam

 

Can be from 25>45 rwhp

 

I gained 25/20 at the wheels with my head swap. But I think the heads are too much for my cam. GT2-3 and GMPP CNC LS6 heads(65cc).

I'm planning on going to a different cam that is better for those heads

 

389rwhp Cam only 420rwhp w Patriot S2 5.3's. 3 year old version.

 

^^^^thats not bad cam only....im liking the patriots more and more

 

30ish ?

 

Depends on your setup, I gained 35 to the wheels.

 

i agree....30-40rwhp.

 

30 ish.

 

My heads were done at the same time I added the underdrive pully and Meziere Electric water pump. The 3 added 70 rwhp and 50+ rwtq. My heads are in my sig.
Cam only I was at 403 rwhp and 380 rwtq. I will be updating my numbers after I spend some time at the shop with a local tuner to finalize my tune. I had to get back to Michigan from LG in Texas and we needed to cut a few corners so I didn't get in trouble at work. Wish me luck, looking for a few more ponies and better drivability.

 

AFR 205 heads gained me 47hp.

 

maybe I should also ask which cam your using to get your numbers

 

G5X3 cam with AFR 205's w/59cc I think the cam is 114
Does that help??

 

that's a big boy cam
