Imho... the only real problem with'em is that the oils aren't made to support the loading. So you need to use an oil that can handle that load.

But why?? Why not use a roller cam that reduces the friction and is easier on the timing chain for instance?

Since you aren't using the ride daily, if it wipes a lobe or two ( and it's been known to happen almost instantly) I guess it won't be such a bother except for all the fine metal particles that'll be passing around in the oil... and lodge into the main and rod bearings...

It's your money / choice.. I'll be curious what you decide and how it works out.
