Which headers with angle plugs?

I have an engine about to go in my 92 RS with a set of GM 292 angle plug heads. Which headers would fit with these heads?

The car has sportline springs with bilstein shocks and struts so its lowered a little. I've been told that hooker supercomps will hang too low with a lowered car, and my searches here have informed me that headman makes a set of full length headers that will fit angle plug heads with more ground clearance. The only thing I don't like about the headmans is that they are 1 5/8" primaries and I would like 1 3/4".

I'm not against shorties if I could find a set that fit angle plug heads.

All help greatly appreciated.

What size is your engine? 1 5/8 will support a lot of power. I have seen posts that larger engines made more power with the smaller 1 5/8 over 1 3/4.

Its a 350 bored .040 over. The guy building the engine says that it should make over 400 horses at the crank plus I'm planning on a 100 shot or so of N2O. I always thought that the increased flow of the 1 3/4" primaries allowed the engine breathe better, producing more power. I guess I stand corrected.

By the way, the car is not a daily driver....only about 25 miles a week.
