I would leave it alone if this is going to be a street car. You will never notice the hp and tq gain or loss from a new set of heads unless you are pushing the motor to high RPMS

It's just gaskets and time to try the AFR's. Go get some time runs at the strip with your current heads then with the AFR's the following week.
Then report back to us what you've discovered.

What are the combustion chamber volumes on each head? Be careful , if you change over, that the AFRs don't push the compression too high.

I wish I had friends... that would just give me some AFR heads...


if the combustion chambers are the same, it would be interesting to see any difference in 1/4mi mph's and 'butt dyno' feel

If all else is equal and it's just a difference of aluminum vs Steel, go with the aluminum. Not only will it save a few lbs, but you will also have a better heat exchange and control. Generally with aluminum heads you can run a higher compression ratio without getting spark knock. Figure at least a full point higher compression and your engine will still run as it does right now.
