Ok, I am sick and therefore do not have the energy to read all 24 pages.:angry7:

I do have a question though. As far as heat, do you foresee any issues with excessive heating issues at the header flanges?

Feets had continual heat issues on his TT440 Belvedere. Even with 1/4" thick header flanges they still warped and leaked. His motor was an 8.5:1 440.
His layout was similar to yours but his headers faced up and forward in to the turbos.

That question came up way earlier in this thread, I will see if I can find it and update it here if I do.

I don't believe I will have any problems though. There was a member on here that used these same headers on a single turbo build with great results.

Did Feets use Meth Injection or any type of intercooler? I am curious as to how much BOOST he was throwing at it, do you know how much?

The headers will only see more heat than normal on Boost. Using Meth Injection that starts to spray at around 3-5lbs of boost and secondary nozzles kicking in above that should calm down the exhaust gas temperatures dramatically. AIS claims that Cylinder temperatures can be lowered by 250* or more by using meth injection which will keep the headers a lot cooler and should help with what you are talking about.
