Can you get us a picture of the combustion chambers?

If it is the head I think it is it has lots of street potential but little value becuase no one knows of the potential it has. If it is the other head I am thinking of it has also a low value but can work well in street applications with a little bit of piston work to clear the domes on the sides.

Hmm cleaning out the husband's shop huh, that's either a bad thing or a good one depends on the situation I guess.

Hi, I saw your posting on the heads, and I am looking for a set of these with these dates codes for a chevelle I am building right now. I would really appreciate your letting me know if you would be willing to sell them to me. I have another pair of them that are dated in April of 70, that I could trade you if you still need a pair. Please let me know if you would be willing to sell. Please email me if you are willing to discuss this, thanks [email protected] thanks david
