Tom, do you ever feel we are beating a dead horse !


Valve springs are one of the most critical and most overlooked components in your engine. Proper selection of the valve spring begins with identifying the application and selecting all of the valve train components to achieve the engine builders’ goals.

They generally run much more than we do. Probably has more to do with that funky porcupine geometry and bigger,heavier valves. SBCs get away with much less pressure.
