how old is too old for valve springs?
my heads were on an engine in storage with the rocker arms still tight for 25 years. water got in the intake and they have already been redone. but the guy said the springs were okay and re used them all, they never got rusty, but still they have had tension on some of them for 25 years. in my opinion they must be junk, and he should have changed them. this is on a relatively low revving (below 6000) pontiyack motor. your thoughts?
