[Tigers] Headers vs stock manifold

[CoolVT at aol.com]

A while back someone referred to a performance study comparing  the stock 
exhaust manifold with headers.  When I put my engine back in this  Spring I have 
to decide if I want to bother with the headers.   The  CAT version headers run 
so close to things that I ended up putting a heat shield  over the fuel line, 
the starter and the shorty oil filter.  I had to put  "heat protecting socks" 
over 2 of the spark plug wires. They make getting to the  mounting  for 
clutch slave pretty difficult  too.  
As I remember someone had posted that from dyno results the HP  would only 
begin to suffer above 5,000 RPM's.    So, anyone have  anything concrete to help 
in my decision?

Thanks, 
Mark
