My only concern is that my fuel tank is not in great condition and the
exhausts headers run very close to this with only the short firewall 
between

i have out in   a racing fixed extinguisher with several jets on it but i
am still nervous

what is best solution to take exhaust pipes further away from tank , or
am i being too cautious ??

>>>Assuming you have all the necessary components in place, you are likely 
being too cautious.   Having said that, there are steps you can take to 
mitigate any potential danger.

The stock system consists of a riveted-on heat sheetmetal heat shield that 
is faced with asbestos on the gas tank side.   Pantera shops sell polished 
stainless steel covers for this shield which slip over the top, and add a 
measure of reflectivity not to mention loads of 'bling'.

The fellow who restored my car was unaware that this was supposed to be a 
cover, and he accidently discarded the stock shield, leaving only the cover 
to do the job.   I wasn't comfortable with this, so I bought some light 
aircraft engine bay insulation from Aircraft Spruce.   This is fireproof, 
reflects heat, and dampens vibration--all good things.   I stuck it to the gas tank 
side of my shield and all has been well since.

The factory low-performance exhaust manifolds clear the heat shield by a 
fair margin, while the Euro GTS ANSA headers often literally touch it, and 
aftermarket headers are somewhere in between.   The tank can be shifted 
outboard, and the heat shield can follow suit by simply drilling out the three 
rivets which secure it to the chassis rail, moving it over and drilling new 
holes and riveting it again.

now

the key and hearing/feeling the thunder of a big American V-8!
