Has anyone used a Holley carb after installing Vortec heads? I’d like to know how it performed in terms of adjustments needed.

I’ve got the Holley 600 on mine, and after tuning it down, I saw much better throttle response. Highly recommend it!

Seems like the Holley is a popular choice! Do you find it easy to tune, or is it more of a hassle?

It’s pretty straightforward! Just make sure to get the right metering rods and jets for your setup. You’ll want it to match the new airflow.

I mean, if you’re not tuning your setup, are you even enjoying the ride? Just kidding, but really, it’s important!
