mac headers
Some people call them long tubes, but they're the longest mid tubes you can buy.
And 1 3/4 dia primaries unlike most "shorty" or mid headers.
They actually work better than long tubes for some applications, and for your mods and concerns of being lowered they would do great.
I recall one guy who switched from Hooker LT's and TD's to ASM headers and ORY and picked up 35rwhp and 40lb rwtq.
Of course those results will vary, and conditions could have been different blah blah blah but his experience was good, he theorized that the hooker lt combo and td's weren't enough back pressure.
BTW he was making almost 400 rwhp IIRC.
It is my opinion that you dont NEED lt's until you start pushing some serious hp. Of course everyone blindly recommends them because they will always pick up HP over stock manifolds (anything would).
But you may find with your mods that the rks/asm design gives you more average hp and tq (ie more fun to drive) even if they do make a few less peak hp than LT's, which I highly doubt.
JMHO
If you've waited this long, you might as well keep waiting.

BTW, the headers are nice, the fit well and you will see a gain. Also shanging plugs are so much easier. I switched to Longtubes with my Blower motor, they are far more of a PITA then the macs!
I didnt see a set listed for a 93 and dont know what's different but this is 599 with the Y pipe. I would call them about the 93 deal tho
