Here's a pic of the heads:

C8AE on top, C7AE on bottom.

The C8 has more of a kidney-shaped chamber, the C7 is a "D". It also looks like the plug is slightly less shrouded on the C7 head (again, more of a "D" shape), while the area around the plug on the C8 head is rounder.

The C8 heads shown have CJ-sized exhaust valves (1.650") and hardened seats installed on both exhaust and intake.

C7AE and C8AE casting numbers and date codes. Not easy to see, I can go back out and get them if you can't figure out what they say.

I guess I wasn't thinking straight, so I should run the heads I have and look for a different intake. I think I am following now, kinda slow some times.

thanks for the photos on the heads, that is interesting the difference of how they are shaped.
