Mark,
Something else to consider - I have run my fuel line up the back of the
engine to the back of the carb and put a heat insulating sleeve over it. I
did this because of fuel vaporization problems due to so much of the fuel
line being exposed to the engine compartment heat and the proximity to the
stock exhaust manifold and down tube. Also, did you have the headers
ceramic coated? I just had the stock manifolds coated and there is a big
difference in the engine compartment heat.
I would also like to see what the LAT try Y manifolds would do in a
comparison.

Subject: [Tigers] Headers vs stock manifold
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
