what headers to use?

Ray, if I'm reading into this combo right, your really making some power here but giving up alot of top end charge with the small tube headers.

IMO, thers really 2 headers to look at off the top of my head.

tti or Hooker Super Comp headers into a 3 inch exhaust pipe size.
Based on actuall output, *I Think* the Hookers should be better for a track only car being launched like a golf ball and turning hi RPM's.
