Header Flow
I installed a set of headers on my fathers truck and noticed it flows 300-400 more rpm over the stock headers. Does anyone know how much more rpm I may gain over stock manifolds on an L98?

None. The RPM limiting hardware is the TPI. Horsepower is, however, limited by the stock exhaust.
