does anyone know the outer diameter of the stock valve springs? and also, the spring pressure.
I measured (With a tape :roll: ) some sbc valve springs at Napa and they are the same as our exhaust springs. The intake is a bit taller though. I don't know it that's a big deal or not but I'd rather stick as close to stock height as possible.57M-GTE said:I seem to remember someone once saying that standard valve springs from a chevy 350 work perfectly and getting stiffer valve springs from a performance shop (ie: Loper's, etc.) was the way to go.
Can anyone verify this? :?
