Budget headers for small block

Hey guys,

im on a real tight budget for my 340 scamp and i need some headers. I have found these summit brand ones http://store.summitracing.com/partd...4294918680+4294908078+400304+115&autoview=sku

and these dynomax blackjack ones

I know that a set of TTi's, doug's or even hookers would be nice, but i just dont have the money for those right now....Has anyone had any experience with these cheaper brands of headers, or with other cheaper headers that im leaving out? What kind of performance can I expect, or are they not worth it all? Im really tight on cash so im trying to go as budget as possible since its only going to be a daily driver.

Thanks
