boring 400EX to 426

[Aarron]

I am boring my 400 to a 426. What should i do as far as replacing gaskets? I thought about just replacing the head gasket? Thanks!

you will have to get a larger head gasket because of the larger bore you are looking for, i bougt a cometic gaskit kit when i did my 416 no problem so far , the head gasket is made of steel so its better if u wana run high compression.It only cost me about 30 bucks for the whole kit.:D
