SPEEDMASTER ALUMINUM OLDSMOBILE HEADS PRINT-O-SEAL 350-455 INTAKE MANIFOLD GASKETS
These are the ULTIMATE in intake manifold sealing technology!
BERNARD MONDELLO Print-O-Seal intake gaskets for the new SPEEDMASTER aluminum Oldsmobile heads, 350-403-400-425–455, and most ported big block OEM cast iron and ported Edelbrock head applications.
1.540 x. 2.550 .090 thickness.
Velpoloid high-temperature manifold gaskets with Print-O-Seal silicon bead around both sides, front and back of intake ports, and water ports. Eliminates vacuum leaks and insures a positive seal. These are recommended for aluminum intake manifolds.
Item comes as a set.
We recommend using:
Ultra Black silicon for sealing the front and rear end rails between the manifold and the block, and also around the water jackets on both sides.
GASGACINCH gasket sealer for sealing around the ports. Apply the GASGACINCH to the heads, gaskets, and manifold.
Note: This gasket fits the new SPEEDMASTER aluminum cylinder heads perfectly because the SPEEDMASTER head is roughly .180 taller in the roof area of the intake port over stock and also .150 wider than stock.
