Thanks for the advice. The head was used for 5K without issues so I am confident all is fine. I have emailed Ferrea in regards to the valves - identifying them somehow.
The head needs to get to a machine shop to get all the valvetrain components installed (cams, springs, rockers, lifters etc) so i will have them check the clearance as you suggested, why not!
