Prepping for a headgasket job and plan to do a valve stems as well. It looks like there are some special tools the FSM calls for. I want to make sure the seal is perfect so I'd like to use the guide / installer but the prices online for these things are nuts. I saw ASF MACHINE makes one for DOHC engines but no mention of SOHC. Do you guys usually just use your fingers, make your own tool, or buy another special tool for these?
