For those that dont know…. maverick heads are different. You cant just put them on a regular 800 or 1000 and expect them to work. I have calls about this all the time. The valves are larger and are at different angles. Here is a picture showing my 940 regular head piston (left) vs. my 940 maverick head piston (right) you can see the extreme difference between the 2 pistons. Both are 12.5:1 compression.
