Cast # 333882 (as best I can tell).

What's the application, combustion chamber cc, compression ratio, and valve sizes?

These presumably came from a 400 small block, 1975 (smog hog).

Thanks in advance.

Only thing I came up with is 74 to 80 350/400 with 76cc Combustion Chambers.

Sleepy,
76 cc chambers gives you 9:1 compression with flat top pistons. I believe that cast number was also used on 74 Z/28 with 2.02 and 1.60 valves, screw in studs and guide plates.

Sleepy69, I also have a set of these heads & took them to the machine shop today. They said, DON'T USE THEM!!! Apparently they're prone to cracking between the valves. They all agree in this part of the country, BOAT ANCHORS!!! I called 3 engine builders about them. Nobody would bolt them on one of their engines.
Just thought I'd let ya know.

Appreciate the info...Sounds like I need use something else other than the 882's.
