What's up everybody. I've got a couple of questions for you guys. So I've been reading through our forums but still haven't been able to find a definite answer, any help would be greatly appreciated. I'm currently riding around in '92 Civic Si, D16Z6. I am trying to use a D16Y8 HEAD on the D16Z6 BLOCK. Will this bolt right up and function properly? I was under the impression that these D-Series parts were inner changeable.. What parts would I need to change for this to work? Intake Manifold, Exhaust Manifold? Like I said I really appreciate everyone's feedback, time and help. THANKS.
