Yesterday I took time to see What I had for heads, C7JE-A, C4AE-G. CJAE-R, D2AE-AA, C8AE-H (3sets), C1AE-A, there may be more, I`m still looking. I`m thinking any of them will work on this 410, I`m planning on a 4bbl with an aluminum intake. Got to see what I have stashed later today. I did find a Howard cam on line at one place and the lifters at another. Still thinking and looking for suggestions.
