How much are you willing to spend? How far are you taking the engine down, or is it just a block and heads now? If it's together, are you leaving the bottom end alone and just wanting to drive it, or take it apart for new pistons and an overbore, etc.
If you leave it alone to keep it a 454, I say stick with the 049 heads. If you're going to go with new pistons for more compression but keep it 454/460/468, I still say go with the 049 heads.
If you're willing to get a new crank and all those parts, you can stroke it to a 489/496 and then use the Patriot heads on the bigger cubed engine.
You can build a strong engine either way here. Let us know more about your plans, or ask some more questions. Lot's of knowledgable guys here to help you out.
