      Good Depending on Motor

      It's good overall as it looks. It's not perfect though depending on the motor you use it on. The angle is not perfect for every motor and the spring does not always compress perfectly strait. This can push down the O-ring seal unexpectedly Overall though, it works great and saved time compared to the other style

    • Must have

      89 C1500 SBC 5.7 heads Must have tool. Seen a friend using prybar tool and thought there has to be a better way. How else will you swap seals and o rings, clean ports, inspect Valves and port and polish safely??? YOU WONT...PERIOD I see way too many people being lazy mofo, cutting corners, oh I'll replace those seals next time...? Seriously.?
