Default Re: Valve spring issues

This is a sign of poor heat treatment of the springs and or materials.

You can test the rest of them, but honestly if one has sagged this soon, others will also.

Sets of springs are not that expensive, the Isky V8 springs (gray color) I recall are 85# seat pressure and will probably handle the extra weight of the larger valves and higher operating speeds. Afterall, more compression, dual carbs and cam, you are going to rev it!!
