360 heads on 318

If the KB pistons are zero deck ones, I beleive the number may be 167s, then those heads should be OK. If the pistons are stock height then those heads will be sluggish on the bottom end because of their large chambers, which in that case you would be better off with 302 heads or magnums. Below are the specs on the 587 heads. Mike
