Replacing valve springs.
Spring compressor 2078 from KD tools is the one I use (they all look close to the same?)
Roll the engine over using the alternator nut (backwards) and watch for any intake valve coming up ( use #2 for example ) the cylinders are in pairs so, 1&6 are a set, 2&5 and 3&4. You roll the engine until the intake valve comes up and you just see its exhaust start to open, STOP. Now, 2&5 are both TDC so you can begin swapping springs on those two. Repeat this procedure for remaining cylinders.
