3769902 Heads

[Rick62]

I'm getting ready to freshen the motor in my '84 pickup. I took out the slant six and replaced it with a 440 thirty five years ago. I have a set of 3769902 castings that look pretty good. Before I put in new guides, valves etc is there something about these heads I need to know? Good/bad? My truck is a driver. 10:1 compression. Mild cam. Does anyone now the chamber volume on these? Thanks!!

I have a 902 on one side in my 383 RR and a 213 on the other. I pulled them off a truck in a junk yard when I needed a set of heads, and I'm pretty sure that's how that truck came from the factory.

Anyway, I have used the 902/213 for a long time and don't have any plans to replace them.

902 heads....... universal 1974 BB head.

Pretty much the same as a 346 head.

No issues with them.

Same chamber volume as the other open chamber heads....... a nominal 88-90cc.
