    Default VH 308 with EFI heads question...

    I have a 308 with VN heads going into my VH commodore, what brand headers fit best?? Some people say the headers will rub on the power steering rack when using VN heads???

    Cheers.

    HI
    Early commo did get a reputation for leaking racks even with standard exhaust. I think the later racks were better . A suggestion would be to wrap that part of the exhaust or heat shield . If using headers get them coated .

    I had pacies on my EFI headed holden in my VH. They fitted but were very tight around the rack. Rack and header (drivers side) had to be fitted together at the same time. Most brands have a specific header for your application. After many years I have discovered that if you expect dramas when fitting headers you will be right more than wrong.

    Cheers guy's, does anyone know if any of the brand headers differ much in how close they sit to the power steering rack?? So far I have found Genie, Pacemaker, Castle Hill, and Hurricane do a set with Genie been the cheapest $$$$

    My genies clear the rack but my concern is how close it is to the rail.
    Factory steel headers cleared rack too.

    ive got 1 5/8 pacemakers on my vn headed stroker in my VB. i had to beat part of them with a hammer around the rack.

    however part of my issues is due to the hole in the bonnet being cut i have the flat across the bottom 6cyl trans cross member not the raised V8 one. this drops the back of the engine down. if it had the right x member id say itd be right. but that means butchering the bonnet
