Looking for a 10.7:1 piston

Then simply get the 10.4:1 since those are cheap and easy to get.


If you are looking to achieve a specific compression ratio you can use the pistons which give 10.4:1 with a stock head and shave the head to increase it as much as you need. To determine the amount you need to have the head shaved check the cc's of the head.

Hope this helps....
 
Maybe a thinner head gasket

Don't know if anyone makes a thinner gasket...I know Cometic makes a thicker one.

Usually, you will need clean the head surface prior to putting the motor together anyway so it is the easiest way to go...
