Water pump failed. Cam belt ruined and bent valves..

Coming home from work I stopped at lights but the car was making a grinding noise. When I set off it was really sluggish but then it was like someone just turned it off and I ground to a halt. Had a friend with me who turned it over whilst I looked under bonnet and it was obvious the cam belt had got damaged. It had rubbed the casing away. I removed a couple of bolts and sure enough, the belt was only about a quarter it's normal width. Had to get RAC to get home.



So removed the damaged belt and found the bearing in the water pump has collapsed and there was about 8mm of play in the pulley. This has caused the belt to rub on the covers and must of jumped teeth.



Got a new water pump and timing belt and fit it. It turned over but wouldn't fire. Removed spark plugs and did compression test. Zero on all cylinders.



So removed the head. 14 valves are bent. :-(



I removed the tappets and they look in good order.



My question is has anyone used these?

I've got a gasket set with all seals etc, but is there anything else I should be looking for before rebuilding it?
