Apparently soda blasting is an alternative - and sodium bicarbonate (bicarb soda / baking soda) is cheap from like pet food stores.
I've bought bags of bicarb soda for just a few dollars, as it's useful for deodorising and cleaning. I am going to give it a shot myself at some stage but it might be messy. If I get around to it before you get walnut blasting, I'll report back on how well it goes.

Yeah I looked into soda blasting as well, the media blaster I bought is actually specifically for soda blasting.
Soda blasting should work, but not sure if I would be game to try it on my engine without having prior experience with it. Sodium bicarbonate is alkaline and have no idea if any residue would be harmful.
How cheap can bicarb soda be sourced per kg? The ublast place has it 25kg for $55 vs $95 for Walnut shells
