    x
                

    These Fel-Pro gaskets work with both cast iron and aluminum heads. Pre-flattened steel wire ring gaskets have the strength of steel wire sealing with minimum brinelling of aluminum heads. Pre-flattened copper wire ring gaskets will not brinell aluminum heads. They offer superior heat dissipation. Multi-layer steel gaskets offer current leading-edge technology and provide a long-term, leakproof seal called Perma Torque MLS.

    • Gaskets are sold each
    • Pre-flattened steel wire
    • Nominal compression thickness: .041"
    • Compressed volume: 9.1 cc
    • 4.166" bore gaskets can be used on 400 race engines with up to 4.155" max bore with minimal chamfer
    • When using aluminum heads, we recommend gaskets with soft copper wire rings (such as 344-1010). This ensures that the aluminum head is not "scarred" by the combustion seal. Shim style 344-1094 will also work well with aluminum heads.
