The 440 'spec' deck height is 10.725", with the stock 6.768" rod length, and stock crank stroke of 3.75" (use 1/2 stroke for calculating piston height to TDC) 10.725 - (6.768 + (0.5 * 3.75)) = piston compression height = 2.082"
Just about all the pistons ate a bit shorter so the block can be decked. Keith Black #237 has a 2.067" compression height (0.015" below deck) with 5cc valve reliefs and it is a flat top piston.
KB also sells a forged version #9953 with the same 2.067" CH, and 5.6 cc valve reliefs.
Speed Pro sells the Forged #2355 piston with a 2.061 CH, and 7cc valve reliefs. Looking at Summit prices, the KB237 = $319.95 set, SP2355 = $367.60,
Speed Pro Hypereuthic flat top 2.060", 5cc # PH147 = $319.92, SRP forged #21345x, 2.062", 6cc, $490.88.

I could not find a price for the KB forged #9953 pistons?
The speed pro #2355 forged pistons are priced good, but they are a heavy piston. The other pistons will be lighter weight. I din't bother posting the other brands like JE, Ross, etc because they were all over $600 set.
