Hey this is my first post on here, I own a vh commodore with a 308, t400 gearbox, and am currently updating the top end. The bottom end is 336 stroked with chev internals. I've got a set of mild ported vn heads which I need to get machined for larger springs and 7/16 rocker studs for the cam I'm putting in it, but what I'm chasing is some extractors, pacemaker only make extractors to suit my car with an automatic steering rack aka power steering, does anyone know where I can get some good headers to suit vb-vk with a manual rack, any help is appreciated, cheers..
