It's hard to beat that price.....

AFR 230's will have more torque 3-4k. edit- idle-4k

Mine flowed 287 @.400 after Tony was done.

I don't think you'll be able to find anything better than a good ported LS3 head as far as price goes. Should make plenty of power as well with a proper cam.

Take a look at those heads. I know they are a little more pricey then a stock casting but with the smaller runner and smaller chamber I feel it would work pretty well for a road race motor. Give us a call and we can go over them with you.

Wow those lingenfelter come with springs as well, even ls3 valves not l92 ones.

Yup, one of the reasons I went with them.
Just a few pics I have of their work.

for price you cant go wrong with a ls3 casting head, weather it be stock or cnced. cnced should make about 30 more hp over stock ones. i have Texas speed CNCd ls3 heads that have been milled on my 418

I agree. He could maybe run the AFR 215 head(if everything else was perfect), but in the real world with the AFR230 V-2s would probably be a better choice for his hp goal.

Advanced Induction LS3 heads...see my sig for details on my 418 build.

Don't forget the PRC 250cc aftermarket casting heads either! They offer smaller runners while still making big airflow! The result is a head with awesome velocity & a potential to make power across the rpm band! Do you want a 350+cfm runner that is 250cc or 270cc?
