i just found this site from another post. http://www.prototyperacing.com/rocker.htm

they have lightweight aluminum and titanium prototype rocker arms being developed. but the thing is they are using only 1 cam lob profile instead of multiple like the original intent of the vtec honda engines. is there any other companies that make vtec aftermarket rocker arms that dont eliminate vtec? as for i dont want a high loppy idle with a huge came. ahah
