400EX Porting

[CDCHONDAS]

Ok guys I am building a 400 ex engine with undisclosed bore and stroke, but I would like to find a good head porting for a 440 kit. Need some contact info to call some people and discuss. Thanks yall!

C&D Racing did an excellent job on mine for very cheap! They are a site sponsor. Just call them up!

whatever you do, make sure it is a reputable shop, someone with experience. C&D is reputable so i would try them. Laz at GT thunder has a magical touch on almost anything so he would be a good guy to try. check locally to. some local guys can do great work to. i just got my head back from the shop i work at, the mechanic here is awesome, and knows more about atv's and motorcycles than anyone i know.
