[Fot] New vs old crankshaft

[Philip Gott]

What’s the difference between early TR cranks with screws to plug the oil galleries versus those with hex head plugs?
Moldex quoted me $4500 for a ghost
Main crank, so I am rethinking my crank sourcing. I last paid them $2700 in 2019. We shift at 6000 rpm so the billet main is, at that price, a luxury. 
Looking over my inventory, I have a number of usable cranks, but obviously want to lose as little material as possible in the remachining. I have an older crank in good condition, but it has the screws in the oil galleries instead of hex head plugs. Was there a significant upgrade in cranks when they switched gallery plugs? I don’t recall seeing anything about a preferred factory crank.
Thanks and regards to all,
Phil
