Looking to buy a pair of good used shorty headers for the 87 to 96 trucks,put a 85 5.8 in my 66 F100 and the mustang shorty headers I am using point the pipes towards the frame where the truck headers point straight back and should work better.

 

I'm running same engine in my 66 and I have bbk shortys on it, work perfect

 

I ended up using lightning shorty headers
