HELP!!! Manifolds???Huggers???orHeaders

Hi All,

I am at my wits end can anybody shed some light on how well block hugger style header work over standard exhaust manifold & weather the change is worth the $$$ or is it better to put the $$$ into getting a set of headers made & would these flow that much better then a set of block huggers to make the difference in $$$ worth while ???

Thanks in advance still trying to get the old wagon to hit 13 flat or dip into the 12's we ran 13.4007secs on the weekend so we are slowly getting there.
