Will they fit a 283 ? YES . The casting # for the block would help.

Where are you? I have a set of stock 1966-1967 283 heads with a valve job, hardened seats and new seals just sitting here.

How much for the 283 heads? I am rebuilding a 67 283 for my truck and could use them.

I had a set of old Corvette dual-quad 283 heads that I recently gave away. I wish I new earlier, I'd have let you have them.
The 305 heads have bosses drilled and tapped for accessories that the 283 heads lack. Other than that, very similar.
BTW, I wouldn't suggest 70cc heads on a 283 unless you need really low compression for forced induction. 305 heads were 58 cc's and 283 heads were slight less than that, if I remember.
