port and polished intake and heads hp gains?

SammyBoy25 · 06-21-2009

Hey y'all this guy is selling new port and polished heads for the v6 for 200 bucks. They are still in the wrapping so they are brand new. So im wondering how much hp would i gain from the heads alone and if i added the lower and upper intake how much would i gain?

new port and polished heads for the v6 for 200 bucks.... I would think to myself "defective or a crackhead" If you can run them to a machine shop and let them check them, (before you pay) hell yeah def worth it!!
your flow would benefit but the single exhaust would net no gains, if you improve the heads you need to improve all air intake and exhaust to see gains.

I'd say 30-50hp gains

For that kind of cash you can get a nice cam to go along with those heads too

. Then you would see around 60 to the wheels depending on how aggressive the came is and how well the heads are ported. With just heads you are probably looking at around 40 to the wheels.

With just p/p intakes you are not going to see anywhere near 30+ hp on our V6's... You would be lucky to see 20hp... The intakes are not the bottle-necks in our system. It is the heads. Even the split-port heads flow well. The real power in any set up is from the heads/cam unless the manufacturer gave them pin hole intakes...

That being said, if they are legit and not pieces then yes they are worth the 200.

Cam/Camshaft - same thing, not that hard to do, basic automotive knowledge.

Where are the heads from?
