disabling cylinders for class change

[ulrace]

Looked in the archives and no luck; just wondering what the accepted method for disabling cylinders (like a v4 from a v8) is. In boat racing we used to take out the pushrods so the disabled cyleder was an "air spring"   . is this acceptable for rules? like to reduce the v8 of 500" to 250..I know it works; just need the exact method.
thanks
