440/520 Stroker with max wedge exhaust manifolds question

I would say by the time you pay for the machine work it's a better deal just to buy a new one. 20 years ago maybe not. 440 Source has them for 799. The eagle 4.25 crank I bought 3 yrs ago was about 600 after discount. 900 now. I have 5500 in my 512 shortblock assembled including roller cam and lifters.
