Any thought on at what lift you need to be concerned with Piston to Valve clearance?

I have a 350 with AFR 190 64cc heads. My cam currently has a max lift of .502 and I am looking at adding 1.6 rocklers which should put me in the .535 range. The pistons are hypertech flat tops with 4 valve reliefs.

I was just wondering if I need to be worried with the piston to valve clearance?

Thanks

 

well i'd say valve to piston clearance is always something you should worry about. in your case it isn't going to happen but still something to check and to worry about
