Exclamation Heads and intake??

Is it worth the buy or go for something else? Looking to do cam after winter. Let me know your thoughts!

dont get unknown brand heads. PRC heads or AFR will net you some good gains. with those heads your looking at you will gian maybe 20. an ls6 intake maybe another 20. all this at the crank btw. honestly with just heads your not going to get blow you mind gains. but they are a step to that road.

I could give my "No joke, there I was..." story, but I'd make sure that I knew exactly where those heads were coming from. I don't think with that you'll net the gains that you are anticipating with those heads. There are a ton of threads for anyone that wants a set of good heads on a budget.

With the amount of work and cost in swapping heads why chance putting on something that may not give you any gains. Thats not to say that there aren't great deals on used heads remember you have to factor in the cost of having them gone over before you install them.

Yup, ORANGE JUICE is dead right,, I have seen multiple sets of PRC heads go for around 800-900 dollars on this site, Dont get heads you have no Info on, and expect broad power gains. The LS6 intake is maybe worth 15 HP.
