Valve Springs

["Cliff Davies" <cdavies@holzher.com>]

I will be installing a cam with the same profile
as the Piper 270
street performance cam. The machine shop says my
valve springs
are fine, the cam grinder says use Triumphtune
springs. This is
not an engine that will be exerted by any means.
What is the
best way to go? Interestingly, I had a burnt
exhaust valve, the
seat in the head was hardened, the guide was good,
leads me to believe
the spring could have binded?
