Great comments all Thanks.
From what I gather from your responses, if it fits together without the adaptor I can put the sender directly in the head and it should be fine. My plan is to put the engine in the truck over Memorial day weekend. All that's left is cleaning and painting the manifolds and installing the "little stuff" Hopefully I'll be all smiles the Tuesday after. If not I'm sure you will be hearing from me.
Thanks again..
