Ok guys i hope i can ask this with out starting a war on which head is better. I have been up for hours and hours reading b16 and b18 head topics, so yes i have used the search button!!! My engine is fixing to be back from ERL performance, they sleeved and built the complete bottom end of my '96 b18c with 9:1 comp. its being built for around 1000hp but i plan on running 650-700 if i can get it. They are doing their race package build on it for me. Ok so here it goes Which head will be better for my app. I plan on driving this car as much as possible. The engine will have prob. a AEM ecu.

 

I think you are azz backwards. You should fully plan a build with the turbo being the final piece to the puzzle....

 

^hahaha

 

Ya but what if you was building off of HP goals and you have a turbo that will do what u need.

 

Wait, what?? So a shop is building your block for "1000HP" but your deciding between which stock bseries head you want to use? You question isnt even close to a complete one. You did not mention if the head is staying stock or not. Porting? valve train? Cams?

 

Do you think some one would use a stock head with stock internals on a complete built engine? Of coase the head is gonna have work done to it. I'm not spending $4200 dollars to use a head with stock internals. I figued you all would just say "So an so head would be better for ya, cause when its ported with good cams it out performs the other head". but what ever.

 

My point exactly. If the head is going to be ported/polished with possibly over sized valves idk what your plans are, (obviously you havent stated much) then whats the difference what casting style you use? outcome will be the same.
