<VV> HD HEAD STUDS battery life

[N2VZD at aol.com]

I have a full set of new otto parts studs that go for $328.80 at Clark's  
now. (part numbers  C10938 & C10839 )  I am looking to sell  them for 
$200.00. any reasonable interest from some one doing aircraft or racing  motor?
I also have a 9891 cam and matching lifters from a @51,000  WB motor  for 
sale.
Most of my batteries are at least 5 years old (time bombs) with no hint of  
failure yet...
I will probably be sorry I said that!
Regards, Tim Colson
