datsunaholic Posted January 9, 2009 Report Share Posted January 9, 2009 I unbolted it from a U67 head. Does that mean its from an L18 or L16? A U67 head was an L20B head, but the manifold is an L16 one. You took it off a mutt. Quote Link to comment
Guest nateoneel Posted January 10, 2009 Report Share Posted January 10, 2009 (edited) A U67 head was an L20B head, but the manifold is an L16 one. You took it off a mutt. lol a mutt it must have been. :D oK I found a shorty round port header in the seattle area. So I no longer need this one. I will be posting an ad in the right area of ratsun for this header. Thanks again everyone for your help and input. Edited January 10, 2009 by nateoneel Quote Link to comment
Farmer Joe Posted January 10, 2009 Report Share Posted January 10, 2009 so this is the same manifold i just put on my l20b. since its off of an l16 is there any reason why i had to grind a groove in the exhaust manifold, and an edge off the intake to make it work? oh and performance wise, the stock manifolds will keep up with a head anyday. my 620 runs a whole hell of alot better now with this manifold than it did with the longtube header.
