701 61x sbt brand new overheating blown head gaskit

[Harbor]

The combustion ring in that head gasket shows burning from the flame, you’ll have to figure out why it failed to seal.

Sleeve drop or negative deck height @ the sleeve/cylinder in that area or not a flat deck or head, or threads that couldn’t keep the head clamped down are somethings to look for.

Awfully old looking head gasket like mik mentioned

Call SBT and send it back. That's why you have a no questions warranty.

Make sure cooling line is connected at pump. Easy to overlook the obvious.
