Default 429 Performance cam valve/piston clearence issues?

Im building up a 429 performance engine. Im using the stock crank (which as been gas nitrided) new rods and pistons that are stock dimensions. I calculated the pistons should be about .050 under deck height at TDC (top dead center). The cam that i want to run which is harder to pick out then i ever anticipated is gonna have max lift of about .560ish...With that lift will i be running into piston vavle clearence issues with a stock pushrods???

Im trying to save time with this info so i dont have to do a mach up to see if ill have the clearence problems which i normally do.

also im running a cam duration of 235 intake - 245 exhaust im trying to make max power but best streatability...any remarks on this combo would be appreciated

Thanks Vince
