help with D15z1 head!
Posted: Mon Jan 26, 2009 8:17 pmLast week I had my z1 head in the Computertomograph to see how the ports are shaped and if there are some cracks. The head is in perfect condition! So i can start my build! 
Here you can see the slight difference between the swirl (lower in port) and the non swirl port (upper in port)
I'd like to know where can i take some material off to get better flow? bowl etc.
