995-16 valve spring alternatives

By luck,

I you could locate a set of Racer Brown VR-18X Valve Springs, that would be a superb set.

#313 lbs. = Valve Open @ 1.05"
#150 lbs. = Valve Closed @ 1.55"

But, instead of setting the Spring Height at 1.55", you set them at 1.70".

A lighter Load-Rate, saves the life of the Camshaft and Valve Spring, and prevents 'Bulldozing' at higher RPM's.

Worked great with the 1966 273/275 HP 'D-Dart' engine.
