Dougs headers
1. Shorty filter is not a problem. I prefer a shorty over the 90* filter assembly
2. Excellent access to plugs, no problems
3. Doesn't trap the pan.
I get junkyard mini starters and use them. The full size starter I don't even bother with anymore. Hadn't tried a full size with the Dougs, so I can't answer.
4 speeds are a pain with the z bar, no doubt.
The Dougs are a good part and every bit as good or better than tti for less money. I have both brands and buy Dougs whenever the car calls for them now.
