yeah i did see those and think they just looked mega small and different to what i had seen online, thanks buddy, taking the head to the brother in law tomorrow and hes going to teach me how to sort it all out and do any machine work needed so shes looking like shes savedThese engines weren't fitted with proper stem seals just 'O' rings that were supposed to stop oil from going down the bores when the engine is idle optimistically called 'sealing rings' in the manual. Not very effective and but better than nothing and should be included in the head set. Just looked at the head set on aBay and they can be seen in pairs in the bore holes in the gasket.
Thought I’d update you, heads fine! Somehow it’s gone in, through the valve, out the other end without even hitting it! Then landed flat In the piston area. I’m a Lucky man!Good to have someone who can help
