Today, an inspection of the [old] valve guide seals found they were 
brittle.

Then umbrella type valve seals installed, intake & exhaust.

While the valve covers were off, a VW clutch cable got jiggered up & down 
in the drain drain holes [necessity is the mother of invention]; then 
compressed air blown thru drain holes.  The friend performing the work 
said that the compressed air flowed easily, and could be heard escaping 
into the lower areas of the block.

Clever design.

Dunno if anything could be done regarding the head bolts blockage.

Oh well, they seem to run well enough as is.
