911 valve springs

[Ratfink89]

has anyone ever modded a Type 1 head to accept the 911 dual valve springs and pedestals?

I have the valve guides out and a workshop full of 911 engines, and parts, so why not shove a set into my bug

I've never seen or compared them but if you can grab some pics that would be helpful. Currently I've got LS1 dual springs and valves in my heads and if those can fit I'm sure the porsche stuff will.
