I am building a new motor and it has a D port head that has two spark plugs. I have heard it would be ok to just block off one set of spark plug holes and run it.

Also this motor was setup for EFI and
I want to run my holly card, Is there
a adapter for the Dport head EFI to the holly 350?

The intakes are very good. I have heard all bad things about the 2-plug heads. I really think people are scared of them becuase of no experance with them. I never seen one used.
Good Luck

There are adapters avalbile too.

Best intake I've ran was the EFI but can't use them now. Make sure you "peak" the runners under the carb so there will be no distribution problems. In my opinion I would stick to the style head you know works and let someone else experiment.

I personally like the 2.0 intake. It works awsome but you better know your stuff. Bobby
