Its an E plate MFi head, and the EFi head i've bought was from a late orion ghia so I'll presume i'm Ok with valves (most prob buy new ones anyway for peace of mind tbh),
I am interested to find out what the differences are between the MFi RST cam and the EFi Orion 1600E cam though? and the Pulley difference if any?
Ta for the help so far btw
