Help me identify exhaust manifolds?

[bruvvamoff]

I have 2 presumably left and right from a V8.
One is ERC0431 and one is ERC0329
And an intake manifold RS9119
I also have loads of other old Rover V8 parts that are hard to identify.
If anyone can link me to a site that will help me identify them I'd be very grateful.

They look like ancient landrover items.
