Coolant passage porting...anyone have pics? Specifically, where you modify the coolant passage walls by "finning" them, thereby increasing surface area and heat transfer. I know there used to be a site that showed just such a modified housing...any ideas?
TIA.

Kevin Landers' Rotary Resserection site has them, I believe.

Racing beat will do it for $60, under their cooling system tab, bottom link.

 

Thanks!
