SDI heads

I have just looked over a pair of SDI cylinder heads I bought online.
Am I correct in thinking they are not handed as when casting numbers are both visible the heads effectively look the same hand ?

They're not handed, but if they're used heads you nead to make sure both oil supply passages are clear, as only one is used, the other blocks with sludge, and if you don't and get the head the "wrong" way around you'll lose the oil feed to the rocker gear.

That's a very useful tip - many thanks.
