What is the Better Head to Run Open Or Closed for a Tall Deck 427 BBC?

I've been looking towards the Oval Port 3904390 98 CC BBC Heads.
Anyone have any Advice on which is best to use?

Will be running a Dual Carb Tunnel Ram,4.25 Stroke Crank,Used to the SBC Scene but want to Move up to the Big Block now.

I've got a 91' Chevy S-10 that I would like to Build up and Run Street/Strip.

Thanks, all Help is Greatly Appreciated.
