I like the feeler guages that are grouped by a screw and nut so I can take out just one. Also, a 27mm deep socket and a ratchet on the crank bolt is just fine -very controllable and safe for turning engine. just make sure it turns CW only (as you look at it from front of car) reversing it can damage timing. Last, it's a good time to check valve timing. Neutralize #1 intake, check crank when valve has reached 2mm lift.
