Hello I've got a 1960 impala and am wanting to install a new ZZ383 crate motor from chevy dealer. When I look at the specs it talks and the "fast burn" heads having D port exhaust ports ? Do I have to have special D port primary header tube headers or will the typical style ie. Headman elite or Hustler style work ??? Thanks

 

They didn't mention on Fast N Loud tonight with there 68 impala. They put in one of those motors.,.. although I think he said zz5 fast burn.
