[Klattu1929]

I used rust-911, did the usual roto rooting and flushed 5 times until cleaner stopped coming out black. I installed a new head and I didn't want to add rust to my head. So I flushed without the head installed. Made plugs to seal the cylinders, and plugged the head stud holes. Built a dam around the top of block, bit of work but my car was torn apart and i had the crank, rods and pistons removed. Worked great.
