360 Magnum building on an existing bottom end

Good advice here. I forgot to mention ring replacement and timing chain. Also....I had issues with my reground cam and had to use an offset keyway and 3 way timing set to degree it. I should have just used a 9 way adjustable timing set. I went with a melling standard flow oil pump and my original intermediate shaft with the reground cam. 60lbs cold oil pressure but I have fresh bores and .030 over.
