a friend is offering to sell me a set of hooker long tube headers he picked up at a swap meet recently, they are tagged as being for a 401 - 425 - 400 - 430 - 455 I believe.... while I would love a set of long tube headers to use with the 401 I have that I want to eventually swap into my '65 skylark, It seems odd to me that they would work on both the nailhead and the later buick big blocks. also, could they be intended for a fullsize car and not my A body? any info is appreciated.
http://taperformance.com/PDF/TAPerformance_Catalog.pdf Look at page 137, the header flanges show the port difference between nailhead and 400/430/455 headers.
ALL exhaust outlets are separate on a "Nail". The 400/430/455 headers middle ports are right next t each other.
