[Tigers] PVC Valve

[Jerry Christopherson]

All this discussion about PVC valves has brought to mind a question I have
had for some time, and that is, what are the differences in all these valves
on the INSIDE.  They have all kinds of different external attachments, but
what is 

 

different about say a 289, 302, 351, 352, etc, etc. on the inside.  They all
work with the vacuum of the engine, varying the volume of vacuum (air) going
into the engine depending on engine rpm burning any blow by.   Anybody have
any actual specs on what is inside any of these?
