U/S EXH GSKT SB CHEV VORTEC HD

The Mr. Gasket 7505 is a pair of Ultra-Seal exhaust gaskets designed for use with Vortec L31 cylinder heads and Small Block Chevy engines. These gaskets feature round ports with dimensions of 1.50 inches for both height and width. Manufactured from a high-temperature steel core laminate with a graphite-faced exhaust material, they offer stability, torque retention, and excellent heat resistance.

The expanded steel core provides maximum torque retention to prevent gasket failure, while the graphite facing transfers heat away from the cylinder head. These gaskets conform to minor surface irregularities and can be trimmed for modified port applications, making them suitable for original equipment replacement, high-performance street use, drag racing, and oval track applications.
