Rato R500-D Valve Cover Gasket

Rato R500-D Valve Cover Gasket

Fits only Rato R500-D head, AND DOES NOT FIT RATO R500-V

This head has the GX390 head bolt pattern and size, but uses a hemispherical combustion chamber, 5.5mm stem valves, and has longer and skinnier stamped steel rocker arms mounted on their own canted pedestal shafts. This head is rare, and you may only find it in R500-D, R500N-V, and some R460 generators.
