I recently acquired a 504 Ti head with virtually no corrosion(!), 92mm thickness and gas flowed inlet ports. Unfortunately it didn't have valves or valve springs.
I tracked down some good valves, but when looking out valve springs I noticed that there are two different 'wire' thicknesses used for primary valve springs on the 2 litre Pug motors. Some are 3.6mm and others are 4.2mms.
This leads me to ask....
Is there a specified valve spring for the Ti head?
Is there a particular benefit / downside of either thickness?
The head will be fitted to a refreshed 2 litre 504 motor with an Argentine (short) 4 branch carby inlet manifold.
A supplementary question ....What cam would best suit this motor..a standard 2 litre carby cam, a Ti cam or something else?
All advice appreciated.

The motor will be for road use only.
