If you were happy with the performance of the SR combo, and only one head is damaged, then you could buy one head and have it ported to match the other one. That is less than buying two new heads!

But, I agree now is the time to step up if you want more power. IMO, the larger port of the 440-1 will make more power than the SR. And now is the time to get a good CNC port job. I like the 2.25" intake valve option, just make sure the piston valve reliefs are large enough in diameter for them.

The Edelbrock Victor with good CNC porting can match the 440-1. And I like their stuff. But I think it will cost you a little more in both work (pushrod fit, etc) and money since you already have the Indy valley plate, external oiling kit, etc.

I just don't think the B1-BS is up to the task. The B1 originals or MC are a big step up, but will cost even more.
