Question about huge BP's

I did some port sketching last night. Not going to bother uploading the pictures again, but here is the direct link:

The big bridge looks to have the bridge open before the port, where as the smaller port seems to open the port and bridge at the same time.
EDIT: Open earlier as the rotor tip, not a straight line. Also I know the big bridge works and has been used before, but the whole coolant thing has me mystified.

The small one is for a bridgeport that retains the whole coolant seal
the other looks more for a Jport....
here, Ive been working with the small one
I started today. I gave it about 4 hours of work
No work on the bowl or manifold side port ... yet
Im using a dremmel and a small carbide bit. Its all I was able to find
ok, here we go
and this is as far as I was able to go today

My best suggestion is to read through the Engine Building and Porting section over at NoPistons.com. They have a group of very serious and knowledgeable builders over there that make most of us look like first graders. I read through that entire sub-forum before I even bought porting tools, templates or a rebuild kit.

I read the whole thing twice, and I still cant understand how to modify the bowl properly.
I dont have the tools to grind at an angle, thats a problem too
