    That all depends on what you/whomever will be using this particular engine for..
    4-1 is more for upper RPM's
    4-2-1 is for more torque in the lower RPM's (some say gets better scavenging and a smoother running)

    I would go with a Hytec Tri-y replica header, they can be had new for under $200. They are a great header for high reving high compression Vtec motors. Check out Ebay for one. I use a no name 4-2-1 on my B18B1 and it works well for my set up. I am building a Vtec head now and am thinking on going with this header.
