Hot rod,

Thanks, MIke above caught my mistake, I meant 848 head for an inline 6. I'm installing it (eventually) on a 261. Would that change things as far as your recommendation regarding the seats and valves? From my very limited knowledge, I was under the impression that new seats were a necessity for unleaded gas. Are you saying I can run the older seats with a new set of stainless valves?

Appreciate the expertise.
