Almost time for the machinist!

Scrape off all you can so the chemicals will be able to work at it sooner.... I am sure it will be appreciated, just as I am sure the chemicals will eat that stuff up, along with the paint. FWIW, I have never had a shop bead blast a block... it just is not commonly done in my neck of the woods.
I didn't ask him his procedure for the cleaning process I guess I should have. When i asked him about the bore he said he does it in a package cleaning bore hone and cam bearings for 450 I said I would do the cam bearings myself and he said 350! Then approximately another 100 for the heads so I'm looking at about 500 or so
