my first engine rebuild (318) advises

went and measured valve clearances.
And least with stock seals closest valve would have 0.48 clearance, biggest was 0.52.
I measured exhaust side to the start of notch that you see on valve saft below lock to be in safe side.
If i am measuring this correctly and i am not complete brain death :)
But because i dont really know how new seals compare i will be buying those machining tools
