1965-90 Big Block Intake Gasket Rectangular Port
Intake Gaskets for 1991 amp; later Gen V amp; VI, Rectangular port 454 Big-block Chevy allow for optimum flow and performance. Any gasket can create a seal, but a good gasket can do it with less clamping force, and for a longer period of time. The new MP-2N Micropore technology does not use solvents making these gaskets environmentally friendly. When compressed, the gasket will conform to any imperfections on the sealing surface even using lower flange pressures. A nitrile bead around each port opening makes the seal even better.
