Might have to get valve seats and valves and seals from the uk...

The exhaust valves definitely have guides, but no seals.

The symptoms you describe are definitely inlet valve stem seals (and possibly guides). If the compression is reasonable, you won't have to go beyond taking the head off.

It's got new seals and fairly new valves so I guess it's the guides ...
