I finnaly got my pictures developed of the porting ive been doing.



The first is of one of my primary ports







and this is my fav pictures of the secondary bridge









Both are not completly finished. I need to buy some long shanked sanding drum's to clean up the inner most parts of the runner, and the bridge has some sharp edges still, but its comming along

For a first time thats damn good. But do like kahren said, try and smooth the edges out a bit so it flows better.

its looking good, maybe port the primary a bit more? and have the top wall of the primary port a little hiher at the outside wall, more like the secondary

Make sure to clean up the casting in the runners as well.

Looks good. Leave the underside of the bridge full thickness. The thin part is near the top (the closing end) of the bridge. Keep checking material thickness to avoid striking daylight. Radius and polish area at the closing end to protect trailing end of side seal when it regains the flat. Leave no sharp edges anywhere. See picture.

I don't recommend this. For a street-driven vehicle, leave the primary port outlets smaller.
