Description
Our "XXX" series product line is the best of the best that you can have for your machine. All top of the line components are used with nothing but extreme performance in mind. Our "XXX" head makes huge power while still providing reliability for the high-revving, race environment.
The "XXX" head includes:
Brand new OEM Yamaha Cylinder Head
We weld the AIS hole shut before porting on the exhaust side
The same "big" porting as our top end race heads all done by CNC to guarantee every head is to proper specs.
Sand roll finish the ports after CNC porting to smooth out the machining marks for an ultra-smooth port
5 Angle High Performance CNC valve job to cut seats for oversize valves and optimal flow
Oversize titanium valves (Del West) for all 5 valves
+2 Exhaust Valves
Xceldyne HD Valve Springs (reduces valve float and increases durability)
Xceldyne Spring Locators
Xceldyne Titanium Retiners
Xceldyne Valve Locks
New Valve Stem Seals
Valve Spring spacers for enhanced exhaust seat pressure
This head comes complete and assembled as a direct replacement for your machine. If you are wanting similar work done on an existing head, we also offer those services and have other product listings available on this site. Buying this head complete saves time and potentially money. We keep these heads in stock and they will ship after order completion. If you are sending in an existing head for service, the lead time generally ranges from 4-6 weeks. We also find many "used" heads are worn out and need full replacement of guides and seats along with needing ground back flat and we often find cracks or damaged spark plug threads. If you feel your current head has a lot of hard hours, buying a new complete head will save time and money.
*It is important to utilize a piston that is cut to accept +2 valves. If you need direction on cam selection, please contact us as we also offer a wide range of camshaft options.*
