Sounds like a solid plan.

If you already have BT heads, you may need custom headers as I believe their exhaust ports are raised a little. Now depending on your kit of choice, if there is nothing off-the-shelf and you are already in need of custom headers, then carry on.

If it were me, I'd certainly consider Edelbrock heads for a build like you describe. They are common, "plentiful" and for a long time the only "performance" heads readily available to builders. Or if I was after something a little more advanced, as Brent recommended also, I'd look at Survival Motorsports Head for a street build. It has a heart shaped chamber/bowl area which according to reports helps.

Good luck with it and keep us posted.
