As I understand it, they are not all that much better then an Eddy head.

So as a comparison they are a little better. But heavier, use a special intake/rockers, and cost more (quick look put these in the $1100 bare range).

Not too hard to understand why not too many people run them anymore based on that.

I think more circle track guys run them because some rules force "iron heads" on the teams.


The Eddys are a nice, affordable street/mild performance head, but I would run a W-2 over the Eddy in a race effort where cost is not a factor.

I've seen W-2s go 320+ with good air speed and a 15* closed chamber W-2 on a 48* block is no contest, especially if the right guy does the port, chamber and intake work.

Plus, with a little grinding, you can tell the brand Xers they just got drilled by an all iron 340.

+300cfm, they are the best head for the money...
