Hi rcnitronutt

You could use Nova racing head ( didn't like it) and crazy nut head and that head is lighter then stock head (not much but some) and it helps alot to keep the temps down.
The vantage pipe is awesome I have one and it's so much lighter then stock!!!!!
Here's a link to crazy nut

they do not have any pics on it.

Here's my pic on crazy nut head, stock head, and nova racing head
