SR Dual Guide Conversion?

Anybody have additional info on this? I've only seen a video showing how to do it... Any opinions/troubles? As far as I know, you just need to grind the shim side of the rocker arm to accommodate the guide shim and since the guide shims are all the same height, they'll be level and flat with the rocker arms?

it looks pretty simple as well, measure the height of the shim to ensure it matches for even wear on the cam lobe

I don't need to measure the retainer depths or heights right? I don't want to just assume they're all level to each pair. I'll go ahead and measure all the guides though.

You cant just measure the guide thickness, you need to measure the overall height of the guide and valve to ensure that the rocker sits flat, the hydraulic lifter will only account for one axis of leveling. You'll need to grind the guides to get them to match up.
