Inlet manifold...

Next item in the parts box was the inlet manifold - removed the blanking plate, plug and non-return valve (brake servo) and power washed it.

After giving it a good soak in degrease and power washing all the waterways. I noticed on the inlet hole on the carb side was a small lip where the original machining hadn't gone deep enough. So with a half round file I removed it to allow better flow (maybe?).

Then I finished off with a couple of coats of high temp aluminium paint.
