slowstangs right it needs to be checked. the procedure is in the useful stickies thread. or google. if you cant find it let us know and we can runn you through it. but you basically clay the top of the piston, bolt the heads and valve train up and turn the motor over by hand. then check the clay to see what clearance you have.
what i would do is mock up your current cam with the pistons you want. then see how much room you have to play with. but it will need to be checked again once you chose the new cam because there different variables that account for clearance.
also you maybe able to get knotched domed pistons to better help clearance.
