Default srp 9.1 comp ls pistons in B16????

hey I have a set of srp 9.1 to 1 comp pistons that are 81.5mm and are for a b18a/b and my question is can I use these in My b16 without any valve clearance issues. Or will I have to grind out the valve reliefs for the vtec valves and it will have blox type b cams. Please someone help me out. I also do not know the part # because its not on the bottom of the pistons. thanks

post pics please, most forged pistons have huge valve reliefs regardless if there for vtec or ls motors.

I should have .022 inches piston to deck clearance according to the zeal compression calculator. I just want to be sure but in not trying to put it together and clay it to find out I just have to take it apart and get other pistons. thanks
