summit shortys?

after a little exhaust discussion with a buddy, he directed me to the following link for headers for my 360. i dont know much about summit and if this pasrticular item is worth the $300 tag.

any tips? my 360 is complete minus exhaust manifolds/headers and carb so im trying to start bringin parts together for when i rebuild it and these shortys look like a good deal and wont scrape
