Points for non-stock pistons or higher compression ratios

[richard]

Are any points assessed for non-stock pistons, like J & E, or higher compression ratios?

[Steve Grosekemper]

There are no points associated with a piston change that has the same compression ratio. You can replace your stock pistons with J&E or any other brand, however when the compression changes there is a 5 point penalty.

Here is the exact rule from the rules page.

Non-stock heads (includes changes in valve size, porting/polishing,
flycutting, or compression ratio changes by any means 5-points
