Valve shaft seals – Shopping list

Hello together, since I want to renew the valve shaft seals in two weeks, I am just putting together a “shopping list” – this consists of: 1. Valve shaft seals (Volvo original) 2. Simmerring camshafts (4 pcs.) 3. Sealing/Sealant valve lid (Is there actually a seal or is one always working with “liquid seal” – Which do I take there?) Have I forgotten something or too much – or does it look good? And…can someone use a tool to hold down recommend the valve springs or pull out the old VSD?
