Im trying to check the v2v and p2v clearances, just need to know exactly how to lock rocker arms to check clearances while vtec is engaged. The c-speedracing website says to swap rocker arm pistons to clay motor, is that the same method used to check v2v clearance cause i read (1 2 N V)'s write up and he suggest to stick a BB into the rocker arm, exactly where does the BB go?

 

its either/or. swap vtec pins or throw a BB behind the small vtec pin. both methods work just fine.
