LA head question.

Are you sure they aren't 974?

576 is an over the counter only version of the 308.

No they are 4343475 off a 86 360. I googled them and came up with a few hits that said they were the same as the 308s which is why I asked.

The motor is a non roller block, 360 4bbl with a Q-Jet. My old 69 Barracuda had the 576s on it. Never knew what they were till I sold the motor.
