Head Work??? Who?

I want to get my head done.... So who does good work?

I'm not looking for peak HP but more power everywhere. I want high velocity ports.? I'm running hotcams with a 97mm piston.

what part of california are you from....

Big Gun Exhaust


has done head work on YZ250F's that resulted in huge power gains (3-4 over stock). It was expensive at $700, but for that kind of power gain ( it would take a 48 hoorsepower YZ450 to 53 at that rate) using stock cams and compression, it's something to consider.

I'm in San Diego.

Has anyone heard of Kenz cycle tech in AZ??
