I want to get rid of the Edelbock headers I have.The AIR tubes are in the way and I want to step up to longtube headers.What is the collector size?Also what is the primary size, 1/2,5/8,or 3/4? If its 5/8 primary,they should still flow better than the Edelbrock 5/8 shorties.

I believe that they are longtubes, but am not sure what size, I was wondering this same thing last night. Also, I'd like to know how much ground clearance you give up when going to any of these full length headers...

But, another thing about the $79 Summit headers are that they are not of the highest quality, the flange thickness is real small, and you might have problems with exhaust leaks. But, if you don't have a problem cutting them up, a good way to stop the leaks is to cut the headers between the two inside ports and the outside ones, so they each basically bolt up seperately. Then cut the gaskets also.

Had this on my old 77 Camaro with cheap-o Flowtechs, and doubled up Mr. Gasket gaskets. I never had any problems with ex. leaks, but they were a little bit of a pain installing...
