Re: crossover exhaust question

Thanks Pat
Yeah that and giving the plug leads clearance was high on my list. The photos make it look impossible, but the plugs are real easy to get out. These photos show a little bit more of the plugs !!

Thanks Cliff
I’m sure I caught the illness from my old man, he’s a fitter and turner and has always made everything himself.


Thanks Frank
Spent days making different dies and in the end it turned out to be quite a simple piece.
A short pipe slides onto the jig and is pressed on two sides, than rotated 90 deg and pressed again (with clamps on the first side). The collar is for getting them off after pressing. The other tool is for getting a tighter radius to fit the flanges.
After welding them from the head side, the flanges were machined flat.
Hope this makes sense.
