H405CP versus stock magnum 5.9 pistons

..
I stumbled onto the h405 cp. It lists a compression height of 1.637 in. Everything I found on the dished magnum piston shows 1.612. The magnum pistons were .045 down in the cylinder. Am I right. Will this be an acceptable replacement with a low price?

I must have missed the part where low price and replacement didnt equate to a purchase? "Get smart' wasn't directed to you , it was refering to a planned purchase on the cheap if anyone did not want to have to buy slugs of $$ Tungsten to counterbalance a heavier piston.
I would not trust a machine shop around here to balance a crank as I have 3 places in a 10 mile radius that only balance cranks. Im spoiled living in a large metroplex with a heavy aerospace presence.
