Over the last 2 weeks or so, i have been getting parts together to do headers and LS6 intake swap on my 99.

This is what I already have:
TSP headers & x-pipe (in transit)
LS6 intake manifold
P&P throttle Body

I have an email into Gene @ GMPH.com for the following:
LS6 intake manifold coolant pipe
LS6 coolant plugs (2)
Exhaust manifold Gaskets

Question, will i need a TB gasket?
What else do you guys suggest i do while i have the exhaust out and intake off? Other mods or maintainence??

Thanks all
