<VV> 140 heads MY opinion

[N2VZD at aol.com]

i have been running 140 heads on my rampy for @10,000 miles now.  i  feel tha
t most failures of the valve seats can be tracked to any signs of past  
overheating or valves adjusted a touch tight (as loose as you can do without  noise  
is better, because of time spent against the seat getting rid  of heat). some 
of the valve seat trouble may even be in the selection of  lifters. some do 
not have the travel of the original corvair lifter. i weill be  removing those 
heads soon for other reasons , but they seem fine so far.   they had all new 
valves and such done when i put them on.only thing i watch very  carefully is 
any signs of pinging...but i think the octane cut pistons are  helping a lot. 
next engine is a 140pg (RN) with no octane cut , and 95 heads for  the 64 coupe 
with a/c and a powerglide.
that's my take on 140 heads. you just dont ever want to hear any signs of  
pinging or detonation , and they seem to treat you like any other corvair  heads.
regards, tim colson.
