I'v been thinking of getting some headers for my car. I was planning on going with the TES ones from Edelbrock but then I came across a deal on some zz4 heads that I could not pass up. Since these heads have D shaped ports, will these headers still work or will they cause a problem. What size headers should I go with, 1-3/4 maybe, if I can't use the TES. Which would you recommend.
Thanks

 

First, please read the "Whats the best headers" sticky post at the top of this forum. Second, click on the SEARCH bottom at the top right of this forum, and type in headers, then read the threads that the search finds. Third, forget about Edelbrock headers. Fourth, if you still have questions, tell us what engine you have and what your plans are, so we can better make a recomendation. Thank you.
