The 301 Pontiac was a bad motor.
I owned one.
At least they burned oil prematurely.

My brother had a nice car (for the time),
1981 G-body Grand-Am,
with a 301.
He bought a 4bbl intake for it and I nearly fell over when I saw it just had 4 ports. Confused

Horrible idea,
 that whole engineering team should have been sent to the mail room to finish out their careers.

The engineering team was promoted & went on to design the Pontiac Aztek.

I'm glad to hear their punishment fit the crime! LOL

Not familiar with the casting number, but it may be a late 69 or early 70 production.

I had a feeling it was a later years casting. Maybe it was intended for Jeep division, since AMC had dropped the V8 on their cars after 79.

When I first got them I thought they may have been welded up. Once I started to klook at them I came to the conclusion they are cast that way. And Rick Jones has a set too.
Mine came from a guy that had a back door to AMC racing stuff but he didn't remember anything about them.

I had two sets and they both came out of AMTech.  The first set went on a 304 stroker that I built but, I will look at the second set to see if they have the same part number.

I see the shapes better now with the other pictures. I would not use those heads on my lawn mower. That is a terrible choked up runner if I ever saw one.

The 3 cylinder heads that I have are embossed with 3233344-1 or -2 and have 304 valves in them.  I don't know what the part number was on the pair that I put on the stroker engine but this is what Greg said at the time.  "These heads are AMC R&D 360 heads. They had 1.787” intake valves and 1.68” exhaust valves installed, and a swirl-port design. AMC was testing them out to see how emissions and MPGs could be improved with a lean-burn swirl-port design. I had hardened valve seats installed on the exhaust side, so that the smaller 1.50 diameter valve head could be used."  I assume he is correct on the valve size but I can't remember.  As mentioned all 5 cylinder heads came out of AMTech so I assumed that they were all Research and Development heads.
