Can someone please tell me which gasket this is that has the red arrow pointing to it.

I just bought a 2003 LTZ-400 with a Wiseco 440, 13.5/1 compression kit from Ebay. Unfortunately, on my first ride this seal began to leak unbeknownst to me. Anyway, the bike ran strong but after it got hot, it would not continue to idle or start. When it did start, it ran fine. No white smoke out the exhaust that I could see. I did then notice the coolant burning at the place of leakage.

According to the seller, this bike had this kit installed and gone over by a mechanic and then sat for about a year. Would you recommend replacing all seals again while it's opened up?

The Wiseco kit states that it comes with a Top End gasket.(PDF Parts list) That's why I'm asking which gasket that is that's leaking. Would I need to order that Wiseco top end gasket and 2 gaskets that are stock suzuki for head and base?

Thanks,
Josh
