Hooker #5303 headers for street Ok?

Currently have 1 5/8 typical headers by dynomax jet hot coated. Still in good shape just plan to improve breathability!:) The only thing is changing out headers. What a pain!! I remember putting these in. With engine hanging on cherry picker. Not fun.:eek:
Agreed with the others here, You don't need more header, at least not yet, and refresh My memory.....are You indeed running a stock stroke 360 in Your ride? You haven't said, so.... a 408 would be a slightly different story, and planning to use a header that may be less than ideal could result in putting up with less torque after working to install them.....only to have Your plans changed for You...................
