header question

[revized_DX]

have been looking at getting a header for my EF. looking around a little bit and always seem to end up on ebay looking at the headers they have for sale on there. my question is...would i be ok with getting one from ebay or i have a shot at getting a ZC header from my homeboy who is parting out his 91 hatch si. which would be a better choice or what is gonna be my best bet? with the famous american economy money is kinda tight and this is gonna be my christmas present to myself!

thanks in advance!
ready for a good discussion!

i am running a Z6 block with a NO-TEC jdm d15b head right now, had to do something quick with what was available...i know its not an "ideal" pairing
