<VV> make Corvairs less "aromatic"

Tue Oct 12 00:49:49 EDT 2010

Six head bolts?

Oh, you did the non-rusty ones first?

Let's see how many studs you can unscrew on the OTHER six!

Got a spare head that you can send off to the machine shop WHILE you are 
removing this one?

Oh, you DID keep the balls with the rockers together and know which came 
from where, right?

Later, JR
