torque is daaang aggressive..that is why i have a 454 in my truck.  How
many miles does that engine have?  I really think that you might be
robbing peter to pay paul by selling the headers.  Turbos like headers. 
Do you already have forged pistons?  If so, then go for it.  I had just
assumed that you were doing a rebuild.
