Default New Head for 400EX

I have a 99 EX, the motor is .20 bored over, with Advance Key Ignition, Rev Limiter, Hinson basket and plates, and springs, Curtis Sparks X-6 Exhaust, and 39 FCR Carb.

Since I will be getting the motor taking apart , since my gears are messed up I was going to install a different Head and Cam.

What is the BEST HEAD AND CAM for my set up????Text

ANY FAST FEED BACK LET ME KNOW, I WILL BE SENDING THE MOTOR OUT IN A DAY.

THANKS

What did your engine builder say? Who are you using?

Default New Head for 400EX

My engine builder did not really say anything yet. The mods I have now I did last winter, the new cam and head work , and transmission I will be doing this winter.

I went through Alaska Drag and Bike for the motor bore over, with Honda of Anchorage to do the assembly work. Drag and Bike customize in motor work, and not really the transmission work, so HOnda will do my transmission work.. The choices are slim unless I ship my motor somewhere in the Lower 48.

What kind of horsepower would I be looking at with a motor .20 over and a head port and polished with a HotCam??
