close, but no cigar !
No, i am getting some laser cutting done at the end of the week and was going to get some flanges cut in stainless, but i need a template from the gasket. At worst i will have to take the old exhaust manifold off tonite and hope the gasket comes away in-tact. I have to get it drawn up then, which doesnt take to long
hmmm...some members might be interested in manifolds... I don't suppose the routing of the headers will be even remotely usefull on the standard car, actually no scratch that. They won't at all will they.
Good plan (for his kit car project) though. 
unfortunately, you are correct. its for the kit. However the flanges would be universal, you'd just need to make up the pipework away for the 'standard' car.
So if anybody wants a set ? !
The manifold pipwork on the kit will be significantley different as the pipework will need to come out horizontally and then turn down. All in time, will become apparrent.
Stainless is good for exhausts as it doesn't rot and its extremely durable and hard wearing, there is some thermal discolouration, but i think that adds to the character. You can also run a slightly thinner wall, so its lighter.
