i have a fully built, bored and sleeved ls bottom end thats going turbo, my ls head is crap now so im just going to replace it. i have a buddy thats got an itr head and a b16 head... which one would be the best to fully build and put onto my motor, like doing everything, pnp, valve job, etc... just let me know if there is anything specific you need to know about my motor to give me the bext advise...

 

they're more or less the same head... if you're doing "everything," then i'd just pay less and get the b16 head. no brainer.
