does anyone here have ported heads for a 3v 4.6?? if so how much hp would i be looking at with them??

 

I'm running ported heads (see my sig). How much power depends on what you already have and what you are planning to do. I'm kind of dissappointed in the heads considering what I spent on them. If you are going to go big with a built motor or really wild cam, they can be worth it. For simple intake, cam, header combinations, you are going to loose a lot of low end torque and not gain very much top end HP. I have grown accustom to not driving my car below 2500rpm in any gear.

I plan on running a stroked motor by the end of this year and a twin turbo next year, so the heads will be worth it eventually, but if I were to do it over again, I would wait on the heads until it was time to do the motor.

 

right now i have comp cams stage 1nsr cams, long tubes, cold air, custom tune, 3.73, udp's, and really really soon i'm gonna get the delete plates...i just wanna know if i spend the money for the heads am i gonna get some good power...

 

Not with what you have now.

 

+1 from what I hear with these cars, the only time you see gains worth the money is when your running a really aggressive, high RPM cam. I've also heard that once you get there, you're intake becomes a restricting factor, but someone please correct me if I'm wrong.

 

i just seen a very good pair of heads that was ported by a nascar shop thats a pretty good deal. i spoke with the mail ford tuner in the area where i live and he said up to 25 to 30hp after he would retune the engine for the extra air.

 

i dont think heads are worth changing unless you go with a stroker motor with stage 2/3 cams and intake
or if you are running big boost
unless you have those, you wont see much gains, and not worth the big bucks.

 

not worth the cost, from what Ive read and heard. Even Brespeed said the gains are not necessarily worth the cost, I had asked when inquiring about the C&L intake manifold/stage 2 nsr cams(127200).
