so first off im ready to do a 16 valve conversion now just need some more info. i have heard that the first gen 2.0 dohc head is the simplest head to swap on. what makes it easier than the second or third gen. i plan on running a custom intake and exhaust so that i can use the stock distibuter and junk. another question is what holes do i gotta plug on the head i would like some more pictures or info on that. also my last question is about injectors and what choices do i have for them i plan for 400 horses in this lbody so i have been told 72pph will do well any info would help and yes i have looked most of this up and not found a whole lot before asking and these are my last questions un answered
