I would be jumping all over CC to get them replace free and compensation for having to fix the problems due to inferior parts failing up twocents
I have the Mopar brand on head valve spring removal kits for both the LA and wedge motors, they both work well up
I had used the Lisle brand single screw onto one valve spring at a time tool before buying the Mopar kit, once I used that kit I put the other ones away work
I have different size valve seal O rings that are for GM motor that I use to hold valves in place when I'm setting up the valve springs before installing the permanent valve seals scope thumbs
