89017465 Gasket kit, Production "Vortec Design"
This is the production gasket for all Vortec design cylinder heads (four-bolt attachment of manifold to cylinder heads P/N 12529093 and 12558060).
Technical Notes:
This gasket requires the use of GM attachment bolt P/N 12550027 (8 required) because the bolt has a ball design on the end that seats in the head so it will not crush the intake manifold gasket. This kit includes (2) gaskets.
