A Threaded headset.
The first BMX frame to feature an integrated headset was the Haro Master, introduced in 1986. This innovative design helped streamline the frame's geometry and improved the overall performance of BMX bikes. The integrated headset design has since become a standard in BMX frames, contributing to better handling and aesthetics.
BMX headsets can be used on scooters, but compatibility depends on the specific scooter's design and headset size. Most scooters have integrated headsets, while BMX bikes often use threaded or threadless systems. It's essential to check the dimensions and specifications of both the headset and the scooter to ensure a proper fit. If they match, you can successfully use a BMX headset on a scooter.
The headset is a set of bearings that allows the fork to turn smoothly in the head tube of the frame w/o sticking wobbling around when you turn the handle bars.

Bicycles don't have head gaskets, the closest thing is the headset, the bearing between the fork and the head tube of the frame. www.bicycletutor.com, www.sheldonbrown.com and www.parktool.com are good sites to read up what's wrong and what to do about it.
When choosing flatland BMX frames, consider features like lightweight construction for agility, short wheelbase for maneuverability, integrated headset for stability, and strong materials for durability.
Yes its very fun.
