valves for small block 587 heads
I like just using brand new valves, feel like it is one half of the valve job having them ready to go. Then they stand up higher in the chamber because they have not been ground sitting in lower like a used valve. Standing up higher adds to better compression ratio.
Then new valves have the new stems so they fit tighter in your existing valve guides, unlike used valves being worn down making the guides looser. Not to mention not having to clean all the carbon off a used valve and grind the face to fit the seat.
Check your valve seats in the head, maybe a light grind if needed, lightly lap the valves in with some compound, new seals and you are good to go.
