Im going to be building a Ls motor, and will eventullay be boosted. Everything is goingto be stock. So my question is, what head would be better. A B20 or a regular Ls? I want to make good power stock so I need the best flowing one. Thanks in advance for the help.

 

they are the same heads, unless you get the p8r head wich has bigger vtec sized intake valves.

 

Wll woudnt the b20 have bigger dome for the bigger cylinders?

 

Anyone?
