Found WTB: E12 cylinder head

[AustrianVespaGuy]

Mine seems to have a problem on #4 

 

Gotta be E12 to fit my pistons, don't need a cam but would prefer one with rockers and shafts if possible.  Obviously serviceable/not cracked, please! PM me if you got one!

How do you know, solely from low compression, that you need a new head? You might need a new head, but not necessarily. 

 

A leak-down test might provide more data, as might a scope of the combustion chamber through the spark plug hole. But, unless you have evidence beyond the compression, you probably shouldn’t consider your current head a goner!

Valid questions! Leak-down test will happen tomorrow to confirm, but I *just* put the engine back in after a full teardown and reassembly, so I'm pretty confident I would have noticed anything on the shortblock side that might have caused this, however something like a bent valve or poor valve seat could much more easily have escaped my notice.  Should have more confirmation tomorrow though!
