They are threaded internally, yes. So they are for the rocker cover….good. I hate having left over parts. I have near enough been exact to the bolt so far (a few originals were too far gone)
I have the standard Perfo air intake – only thing 11D is the crankshaft and associated parts.
Now for that spacer – I could do with a close up photo of Distributor mechanism as I think it may be something from there, not sure.
