DIY Soda Blasting- Engine Top End

[5twins]

Yes, I think I used an old head gasket for the big covers. The plastic cup covers over the bottoms of the bores are ready-to-spread frosting containers, perfect snug fit over the liners that hang out the bottom. In fact, you even need to warm them with a heat gun a little so they slip on easy. The plugs for the exhaust ports were cut from an old baseball bat. It's perfect because it's tapered and lets you make a wedge-fit plug. The little eye bolts were added so I could yank them back out.
