I did a quick CAD model of the exhaust flange and water cut one to try for size,
if this fits ok I plan to make to flanges of 3 joined together , then the header will be 3 into 1 for the front and rear 3 cylinders then 2 -1 to match up with my z story system, I've ordered some stainless tube and some 3 into 1 collectors ,
I made this a while ago in work when it was quiet , so now I can make some 1 1/2 dies and use it for something useful , bending the tube for the headers ,
I also brought a RB front cam wheel cover to maybe modify and use or at least get some sizes off and make one . the rear part i already had has been 'clearanced' and put on for now to give me an idea of where I need to insert bits to effectively seal the top section to stop oil going everywhere in the engine bay.
I cant really get the head into work at the moment and machine it as we're still doing prototype ventilator parts and Ozone generators , so all the machines are set up for small runs of parts , So trying to get on with other bits that need sorting , like an oil take off for the head form the oil pressure switch, header sorting etc
