305 heads?

I have an '88 305 TBI car that im parting out and junking... i don't know the code of this engine, im sure plenty of you know it off the top of your heads. ANyways, are these heads worth pulling? were they the better flowing 305 heads or was that a carbed version or otherwise? The engine only has about 140 thou. on it, so ill pull em if they're worth the trouble.

TBI heads...enough said. No they aren't worth pulling. They aren't worth the effort of getting the tools out to begin to pull them.

They are the swirl-crap heads with the uniquely-stupid ramp cast into the head which "swirls" the intake charge for low end torque, but anything above about 3000-3500 rpm, and they are nothing more than a flow impediment.
