I've seen basically two versions of "Big Valve Heads" offered.
One by ScrappyDog for about $130 and one by 02starrider (ebay) for about $35
Looking around forums, best I can tell the Scrappydog BVH has porting and the 02Starrider head does not.
But I'm not positive.
The general consensus is that without supporting port work, the budget Big Valve heads dont do anything. But I am not sure and research hasn't really turned up any solid information.
Has anyone used the $35 big valve head on a BBK and what are your impressions?

If you dont have the intake and exhaust sides upgraded to match and dump more fuel and air you wont notice much if anything at all by just slapping a big port head on..more air/fuel in,,more air/exhaust out=better performance
