Man, you just keep striking out with things I am dam sorry to say!

1970 HO heads would have a 87 CC chamber since they where used on a 455, this would give your 389 only some 8.5 compression.

Next those 955 spring are for race only with big time pressure.

Those rockers would work if you yanked the heads off and had screw in studs installed and ran hollow push rods like you have, but of the needed length,
