A valve seat must actually do several things – it must support and seal the valve when the valve closes, it must cool the valve, and it must resist wear and recession. Consequently, seats are under tremendous stress. That's why regular maintenance, including regrinding or replacing worn seats, is essential to extending engine life.
Valve seats come in a wide variety of materials, different combinations of alloys, powdered metals and super hard materials designed to prolong the ability of the seat to seal against the valve head. That's why Goodson offers six different abrasive formulas for grinding valve seats.
