Inliners International Forums General Discussion Hi Performance Wayne 12 port question

I have a Wayne 12 port head for a Chevy. Will the stock 235-261 head gasket work? If not, what will? Will I have to make my own? Also there seems to be no provision on the valve stems for a rubber seal. Will unbrella style seals work?

Do you have the 15-bolt or 18-bolt head? Which block is its intended recipient? The 261s are all 18-bolt blocks with steam holes. It is not advisable to use the stock gasket, as the combustion chambers are such a different shape.

The stock gasket may work for a while. The Flatout Gasket Company may be able to make a gasket. Are you a member of Inliners? There is still an active group willing to help a member with a 12-port head, as that was the original impetus for the founding of the organization. Has your head been registered with Pat Swanson's archives? Click on the Historical link to the left.

I have never used seals with mine, and the oil consumption is not observable.

Thanks for your help. I will check it out.
