thats not totally correct on the b16/b18c1 head on a b16. the b16 head flows better, the b18c head gives you *slightly* higher compression...so it's a question of flow vs. compression. otherwise there isnt a whole lot different about the heads...it's not like the b16 would run bad with a gsr head, it would actually run about the same.
