THESE AREN'T SOLD OUT BUT THEY ARE MADE TO ORDER. YOU CAN CALL AND ORDER A SET ANYTIME.
Griffin Race Heads are known for power.....Now they are known to make even more.
These are brand new and assembled ready to be bolted on. All you need is your camshaft of choice or your stock one and you are ready to reap the benifits of this high flowing head.
These were originally designed to work with the clearances Stage 3 cams require....but will work with all cams.
It all starts with a Maverick style casting made in the U S A (Ohio actually)
Fully Race Ported for maximum flow
(Porting reshapes and opens the the intake and exhaust runners to allow maximum flow and efficiency.)
Larger intake and exhaust valves.
(Larger than a stock Maverick head valves. A bigger hole to flow through.... this is a no brainer. These help to flow more air and fuel to produce more power)
Shorter BRONZE Valve guides .
(Bronze guides have a lubricity to them that is critical when hi lift and spring pressures are used. Under these conditions the bronze guide will last much longer. They will also run with less guide clearance and this keeps valves cooler, and valve job lasts longer.)
High Lift Dual Valve Springs
(to prevent valve float at high RPM's and clear those HUGE cams)
All race products such as this have been tested tough, but do to the nature of the world we live and ride in there is no warranty or returns on these product.
