Hello Sages,

What is the stock Valve length for the slant 6's?

I am out of the shop/garage currently and do not have access to any for a measurement.

Thanks,

Greg

Got to the shop Yesterday.

4.802" OAL which is different than the service manual length of ~4.70" I think the service manual measures from the valve stem tip to the dimple in the center of the valve head. I could not measure it that way with my equipment so from vavle stem tip (rocker arm side) to the Valve head Outer Diameter (combustion chamber side) it was 4.802"
