I want to do a porting job where I do a medium streetport on the 4 ports, then do a bridge on the aux's. I've heard that the VDI doesn't work well with big porting jobs due to the big overlap, so will it be a problem for me?
Also, do I need 1 piece apex seals to run a BP, even a small one? I've just heard that if you don't, a seal will get caught in the port.

anyone?

Not the seal ... But the side corner seal stopper thing...Its rubber and fits on the side holding the apex corner seal in place. It rides against the bridge so you need that bridge. You do not need 1 piece I dont think. They dont seal as well because they expand more when hot so its hard to start in the morning due to lack of compression. I forgot their purpose but for high reving aplications go with the stock 3 pice. The 1 piece is also heavier but it might be soley to prevent detonation on high HP cars.

The apex seal will not fall into anything but what kind of bridge ? monster bridge might be another story.
