I am rebuilding an engine from an Austin 7 "Buroche" Special and it appears to have enlarged inlet valves. The dimensions are as follows:

Length: 3 1/4" Diameter of stem: 9/32" Diameter of valve: 1 1/8"

The valve uses standard tapered cotters, and there is a 5/32" clearance above these on the stem.

Does anyone out there know where they might have come from, and also whether they are available today?

Hoping someone may be able to help. Many thanks!
