mirror doesnt that tool only work with vtec heads? I thought I read that somewhere, sorry if I'm wrong
I have no idea. I know I have seen these before, but dont know if there is a separate application dependent on the heads.
I had my machine shop swap out my valvetrain on a bare head (not installed on the car) for $40.
Theres some other contraption that bolts on either side of the head, and has a swing arm type thing to press the spring down. You dont need to move it for every springs, but you need to move it from the intake side to the exhaust side. Couldnt find a picture of it. A person can probably make their own compressor like that if they have some tools and a piece of scrap metal.
I think its this one.
