Your exactly rite bro I to have used them aswell.. seems like this MR smarty pants has done more reading then hands on. I been building Honda's yotas and Nissan's since I was 14 I'm 35 now it's totally ignorant to think that a person's age may define knowledge or skill...are u fuckin serious.....headers from a single cam wont fit? why not they are d-series kid!!!! when u do a dohc swap into a crx or civic and u use sohc headers how do they not fit....u espicially cant tell ME they wont fit for the reason that i used them onmy swap this weeked...
Great pic to show how lil of a difference there is... I am a welder and fabricator so I usually buy raw tubing and mandrel bends and fab my own manifolds but they definitely bolt up. Great to see you guys know ur shit cause if u ask the internet these questions the tell a person that Dohc and sohc manifolds Rnt compatable but that's just BS it all just cause they want people to spend more money or to discourage someone's build in my opinion. Great stuff guys and nice rex's both u guysthe SOHC exhaust manifold/header will bolt right up, however the ports do not align - not a big deal - you can either grind out the header to match the head or just leave it - we have run them both ways and it doesn't seem to make a whole lot of difference either way - maybe a slight increase in power with it port matched, but you will never notice it in just driving it - here is a picture of the D16A1/DOHC ZC exhaust gasket on the SOHC header showing the amount of mismatch
