Already tried to search but could not find exactly what I needed to know. I'm currently running ctr cams and recently brought some crower stage 3. I also want to change my pistons to increase compression. So will p73 pistons in a gsr running crower 3 need to be clayed do to piston to valve issues? Someone with the same setup or knowledge help me out!! Thanks in advance.

 

not a bad idea make sure vtec is ingaged and you are at the most advanced u think u will ever go with your cam timing.

i would just for piece of mind....unless you like having your valves tap your domes
