retainers for larger diameter springs

@ Marcohotrod, it's not about the springs itself. It's about the retainers.

I'm just on my way to build a mild 5.2 magnum. And when it comes to the point to upgrade springs to use a bigger cam than stock, you may als get to the point, that you will need retainers with an other diameter.

Stock magnum valvesprings are behieve springs. And most of the aftermarket springs are not.

Ive read that most guys in USA going to junkyards and pull the needed retainers there for cheap.

The tricky thing is that magnum valves have only 8mm conc the valvestem.

So it's not so easy to find matching retainers.

Conc the springs the plan is to use HUG1102 (as i can get them for cheap here)
