hi ,i am new to this forum and i am the process of building a b18 ls head. but i am not sure waht to about the vales, at first i was going to get oversize vales, but someone told me to use 2 set of intakes instead , and finally i was told to stay stock size cause once you use oversize the head will not last long.

so what do you guys recommend any comments will welcomed,if it helps the car will be turbocharged
