Important Information:
We recommend to check installed spring seat pressure & open pressure before installing your cylinder heads to make sure the spring pressure is correct for your application.
CLEANING:Aeroflow thoroughly cleaned your cylinder heads prior to dispatch. The heads were washed in a water-soluble chemical agitation tank and blown out with high-pressure air three to four times before being packaged.
During certain machining operations, however, small metal particles can become lodged in the water jackets and may dislodge during transit. Please note that a single chip approximately the size of a 10-cent coin can fragment into many smaller particles, which may make the situation appear more significant than it is.
It is not uncommon, when applying high-pressure air to the water jackets, for additional debris to be expelled. Aeroflow recommends thoroughly blowing out the cylinder heads prior to installation.
