Advice / pointers on replacing valve seal

I have one that is different than all of the ones showing. Has a double hook for attaching to the rocker rod, a double press down, for each side of the valve spring, for an even press and a 14' handle for pressing. I did add a copper tube and drilled holes for attachment, instead of using the rods on the heads, so not to damage them. I bought it 40 years ago and it was used then. Works great!!! Would send photo, but my computer will not read my phone (photo app.) for some reason.
