Top end gasket kit for 416?

[metalmind342]

Ill be rebuilding my 416 this winter and can't see to find the correct gasket kit to buy?

I am right in thinking that the factory gaskets will not work correct? And if so, what gasket kit am i looking for and any links?

TIA

Factory gaskets will work cuz your still keeping the OEM sleeve and size, it's when you go too a 440 or whatever requires a oversize sleeve thus needing a larger gasket.
