Hi would like to purchase 340 exhaust manifold gaskets . Question one will 318 gasket fit are they correct ? I read some were that the ports are different ? Not sure it is a 1970 engine . What would be the best ones to get ? .I know they had a heat shield . But way to pricey .Thank you for taking the time to read this :australia:
Based on advice I received here, I did not use gaskets with the stock exhaust manifolds on my 340. I used Permatex Ultra Copper RTV instead and it has worked fine.
:cheers: thank you
