Hey guys,
Just as an alternative to
Kooks and the others, Accufab has custom headers too
http://accufabracing.com/exhaust.htm#HeadBolts that seem to be up there with kooks and have great quality. They come with a paint that will burn off so i plan on using por 15 high temp paint that looks like the headers below. They also have a black finish. These are the pictures of a guy off the corral took when he sold them on ebay.
I talked to the header guy at Accufab and he is great to work with. Explains everything about all the different designs out there...search on hardcore50.com about some stuff too. His name is George Klass. He told me about the spiral scavenging affect by placing the tubes correctly in the collector so that they pull the gases out better i think. Im still a little confused as to how u build it. And how a lot of guys think too big when running headers...1 3/4" should be plenty for MOST applications. Its like an hour glass...like he told me....the bottom doesnt change how fast the sand comes down. Only the middle part. So having header primaries that are much bigger than your actual exhaust valve is pointless.
Anyway, i paid $500 for these 1 3/4" long tube headers.
