440 pistons Help

Yes, those are the ones, you really don't need to deck the block if you don't want to, just depends on where you want your compression at, but 0 decking will give you a better quench, its not too exspensive decking the block, but you'll have to "mock" up a piston or 2 to see how much needs to come off, but its not really needed, those pistons will sit very close too the top, if you want, you can mill the heads about .030", this will drop the CC around 7-8cc, this should raise compression around .6 of a point, should put you around 10.5 with the .039" gasket, thats if those heads are 84cc now, you may want to at least CC those to make sure, i took a 440 i built & had some 906s milled .085" useing the 2355s & a steel gasket lol, compression was over 12.1, needless to say it didn't like pump gas too well.
