I am looking at some nice shorties for a pretty good price. Assuming that I can get the Ford Racing unequal length headers (P/N M-9430-N95) for $365 to my door, or the JBA (P/N 1624S-4) shorties for $334 to my door, which is the better deal, and how much better of a seal is it? They are both stainless and supposedly the JBAs make great power but people really seem to like the Fords. Please let's not turn this into a "longtubes FTW" thread.
