Those were mostly found on the higher hp small blocks in the '69 and '70 years.
The upside of those heads (if they are the 186 casting) is that they have the higher compression 64cc chamber (vs. 76cc std. in the trucks) and the front accessory holes which are needed for the factory mounting of our alternators, a/c, etc.
Are you having those rebuilt or just re-using them?
Are the 2.02" intakes or the 1.94"?

Like camel humps?? I'm actually putting these on the shelf and installing a set of Pro Topline heads with 2.02's and 1.64's on them. As far as the ones I took off, I'm not sure what the valves or springs are, but they were paired with a Lunati 285 Bracketmaster 2 cam so they are most likey pretty decent. If they are good heads, I have a nice head/intake/cam and lifter package I need to find a home for. That's too cool of stuff to just sit around the barn
