    Would there be any problem mixing the casting numbers on a build? I have one good 906 and need to find another cylinder head but didn't know if I needed to look for a 906 exclusively or if a 062 would work. Also, what is your thoughts on getting remanufactured cylinder heads and sending off a core?

    Take them to Patriot there in Alabama and tell them to make them the same. I bought a take out 6.0 out of a Trailblazer with 1 243 head and 1 799 head. I took them there( I was working on B'ham) and they said they were physically the same just a different building (manufacturing) process. I'll bet They would work but if they CNC port them and do their valve job and stem machining and install their springs you will be a Happy Camper
