Worth changing valve stem seals

Ill look into it :)
Just doing another bulk order on DS, do my cam chain tensioner bits look like they are kaput?
Underdog1:
Got my barrels and head back from the shop
They are just measuring my pistons up for me now as I don't really trust my £5 eBay micrometer.
Still haven't quite wrapped my head around the valves, if they've been vacuum tested and seal well does that mean they don't need lapping at all?
Bryanj:
Valves probably not but definitely change the seals, tensioner is expensive but worth changing as old rubber goes hard and can break causing disassters

Yeah I thought that might be the case, piston rings seem fine but is this one of the 'might as wells' when it's in bits?
Just spent the last 90 minutes getting these boys clean
They were really coked up bad
