75 350 heads good or bad?

Im cleaning my shop and throwing away a bunch of stuff and stumbled across a buick 350 I had for years. My question is, are the 75 and 76 heads 350 junk like the 75 and 76 455 heads or are they actually worth keeping?
Thanks, Tony

 

Hold on to em, I believe all 350 heads were very much the same...... all open chamber

 

Ok. Thats all i needed to know. Any idea what they are worth? They need redone.

 

The 75-80 heads are poor flowing and low performance heads... they aren’t worth much to be honest.

 

Thank you for the reply. Scrap pile it is!
