We have a very wide range of chamber selection due to the motor being used in a number of different machine variations. These heads are all TPI compatible.
As a side note "Stankdog" does not run high compression for motocross. He runs a custom chamber very similar to XC11.

Phathead Kits include a head shell with one combustion chamber, two sets of o-rings, cylinder and some stickers for your bike and tool box and installation instructions..
Phathead cylinder heads are made of 6061 T6 billet aluminum. The material is stronger and transfers heat better than cast aluminum. The two piece design allows an increase in coolant flow as well as surface area which improves cooling for better consistency and performance.
