I Have had these heads for years sitting like dummies on a spare block.Now they go to work as I will put these on the engine Bill built for me and I will get the 35 Ford engine out and put in this one

More to come. I borrowed this test plate which is for a block but also works on a head and made up a sleeve for the water intake and a schrader valve to pressurize it 

Put in about 45 PSI and it passed like a champ!
