I'd highly recommend getting your block thermal or 'baked' cleaned. Your block will be heated to temps at or above 600 degrees and they come out looking like they just left the foundry. No way could I have gotten it that clean myself. Cost may be about $100. I'd Google search or call any engine builder in Miami and they should be able to steer you in the right direction.
$100? Cost me $495 for bake/bead blast. Then crack repair, heli-coil . . .
It cost $125 in NJ. May want to inquire why it cost so much in MA.
Just a note - I used "Rust-911" on the '51 Merc I now have in my '51. I did it 3 times with plain water flushes in between. I thought it turned out well. I have had the engine in the car for about a year now, and I have had no cooling problems. Here are some pictures of the result :
Thanks for all the input. I decided to soak with degreasser and pressure wash as it was not that bad. Also pressure washed the water jackets and got a lot of scale rust out Going to use the evaporust for water jackets. Can't find anyone that knows about the bake process here in Miami.
Thanks to all, Rick

Hmmm.....One of Tod's NEW blocks at $23-2500 is startin' to sound pretty darn reasonable. DD
