Our 2BBLFC copper flange adapters are for applications using two barrel Ford 351C Cleveland and 351M-400 cylinder heads with our FC-series headers.

This flange adapter is required for all Ford 351C-351M-400 engine applications using our headers on two-barrel (2V) cylinder heads. If using 4V cylinder heads this adapter is not required.

    I plan on using Aussie 2V heads. Will I need a gasket if I use the copper adapter, or does the adapter act as the gasket?

    Our headers do not use gaskets, and using gaskets will most likely generate sealing problems. On Ford Cleveland (and Aussie heads---still based on the Cleveland design-) the 2V heads require the copper adapters and then a thin, 1/8" wide bead of silicone around each port that needs to be applied to both the cylinder heads and header flange when using the copper adapters.

    I have 1970 2V Cleveland heads and I want to run the stock Ford 1970 4V exhaust manifolds. Will these plates help block off the leaks I will encounter? Also, what is the thickness of your plates and what is the composition of the metal? Thanks

    I do not have experience using the adapters with factory manifolds, so I cannot provide information on whether or not they will work for you. The material and thickness is stated in the product details ---- copper, and 0.062" thick.

    I am using a set of Trick Flow Heads for Ford Cleveland/400M. Part Number is TFS-5161T004-C11. Can you verify that I need these adapters?

    Look at this image. I believe that the TFS head uses something fairly close to a 2V port dimension, so yes, you would likely need the adapters.

    I am using CHI-3V heads. They have 2V Exhaust Ports raised to match 4V. Do I need adapters with these heads and FC-3 headers?

    You shouldn't need the adapter plates. Although all of our Ford 351C, 351M/40mm headers are built using the 4V exhaust flange, the exhaust surface design, port size, and port shape of the CHI 3v-185 will allow proper sealing without the adapters.

  • Apply a narrow 1/8" bead of Permatex sealer on BOTH sides of the copper adapters.
  • Allow the silicone sealer to dry overnight.
  • Place the adapter between the cylinder head and Sanderson header and tighten the header bolts normally.
