400Magnum

Hello Everyone,

I was hoping to find some information here. I am considering using either the LSX or L92 valve springs and retainers in a different engine since the spring pressures look about right and I can buy these springs for less than the original equipment springs, but I can't find any information online giving the physical dimensions for this springs so I can't tell if they will fit on the heads without having to do some head machining first.

Could someone please provide the dimensions to me or point me in a direction where I can find them?

Thanks!
