Default NOS 428 fitted block

I have an NOS 428 fitted block that has brand new 50 year old cast pistons. Plans for the block are to run a 68 cast intake with RA II heads and a nitrided VooDoo 704 cam, NOS GM lifters, Harland Sharp 1.5 rockers, 428 nodular crank turned .010/.010. The piston valve reliefs and dish measure 14cc. I'm figuring compression will be 9.85:1. I'd like to use the cast pistons with pressed eagle H beams.

Question is, Do I need to / should I go with a forged piston?

Thank you
