Danny and Al, thanks for your comments.
I noticed an occasional popping at lower RPM that was not there prior to the new heads. My though is the main jets may need to up a size to account for the higher head air volumes. I only have about 30 miles on the car since the new heads were put on. I would think I want to wait for a few hundred miles before I re torque the heads and adjust the valves.
I ran into another issue yesterday where the car had no power was running rough and would backfire if pushed to higher than 3k RPM. It would occasionally clean up a bit and then run horrible again. I pulled the main jets and cleaned them, took it for a ride and all was well for about 8 miles and then the same thing happened. I limped it home, pulled off the carbs, tore them down cleaned everything (did’t notice and debis or clogged passages) put all back together and it didn’t change anything.
It idles fine, so my next step is to replace the coil, and then plug wires. I am running the compu-fire electronic ignition which looks fine and my guess is it either works or it doesn’t.
Any other thoughts or ideas on next steps
Thanks
chris
