I am wondering if I will need to notch my pistons for the cams I will be running. The pistons are -23cc dish, here is the info from my cam card

Intake/Exhaust
Gross Valve Lift- .500 .500
Cam Lobe Lift- .3000 .3000
Adv, Duration @ .006 Valve Lift 269 269

Intake/ Exhaust
Duration @ .050- 234 234

Thanks

there is still a "rim" around the top of the piston where the valve will hit, so notching is necessary still no matter how much dish you run IF you are in the category that needs notching.

that looks like a pretty radical cam you have there. what exactly is your application?

whats the LSA* and the ICL*? thats the important info, and just to be safe you better notch them anyways...
