Here's the "new" C4 engine as I left it 3 hours ago, probably they have a huge amount back together now since people were making paper gaskets, flatting/lapping the oil pump cover on a surface plate and throwing Hylomar at it back then!

Perhaps a trip down the road. . . . . . . . . . . . .

You said....

" flatting/lapping the oil pump cover on a surface plate "

My old mechanics instructor just rolled over in his grave...
If ,as an apprentice ,I was to lap anything on "HIS" surface plate,he'd be hanging knots on my head faster than I could rub them....!!!
That was one of the first things impressed on us when we started in his class...."The right tool for the right job"...and HIS surface plate was a precission instrument,a true flat surface, for among other things
Checking for warpage in other surfaces...
Once you lap something on it it wears the surface of the surface plate and you can not ever have a true flat surface where you lapped the valve,as the lapping grit not only wears the valve material but the surface plate material also...
A cardinal sin ,worthy of a group sac kicking if you were caught doing lapping on HIS surface plate..
