Description

CHRYSLER 426 STREET HEMI 4.320 X .043 PRO COPPER HD GSKT

MIA's Description

Constructed from premium 99 percent pure copper sheets, these gaskets are precisely rolled and tested for uniform flatness to ensure accurate cylinder head-to-block alignment and prevent uneven loading. After processing, each gasket is annealed to achieve optimal mating and improved cylinder sealing, resulting in lower leak-down percentages.

These copper head gaskets feature a 4.320-inch bore and a 0.043-inch compressed thickness, designed to suit specific performance needs. O-ringing of the block or heads is recommended for optimal performance and sealing.
