Best Stock BB Heads?

The ProMaxx Head, in layman’s terms is the same casting as the Sidewinder heads, only they install US made guides in them, and do the guide and seat work in the states.

For me the bottom line on those is........ how do they compare price wise to the current industry std for a non-mw head..... the TF240.
It’s unlikely they would make more power than the TF240, and down the road I’m sure the resale won’t be as good........ so the only way I can see those as a real viable alternative is if they are noticeably less expensive....... and I don’t think they are.
Not to mention that the TF’s come with pretty nice hardware.
