Plug gap will depend on output of distributor and fuel being used. Most applications using methanol will be at .022" - .025". If your ignition sytem is a higher output, maybe able to go as wide as .030". Gas application should be .030" - .035". You should also consult manufacturer of distributor for their recommendations.

Fel-Pro P1010 S/B Chevy 265-400 Copper Ring Head Gasket 4.166 In. Bore
SKU-3441010
                        

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 copper wire
  • Nominal compression thickness: .039"
  • Compressed volume: 8.9 cc
  • Recommended for '86-'91 Corvette aluminum heads. Max 4.155" bore.
  • 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.
