Does anyone on this site have a picture of a 240 68cc kidney shape chamber and one of the 240 pushrod slots?

 

If you need help determining if it's a 240 head.

The 240 head will have a large "A" cast in the head under the valve cover area of the head. The 240 and carbed 300 heads( the ones that have slots ) have the same pushrod guide slots. The 300 heads will either have the guide slots or round push rod holes, depending on the rocker arm used.




The 300 will have a large "T".






And the casting/engineering # will also have a "A" in it at the third digit instead of a "T" which all the 300 heads have. And there will also be a large "A" cast into the one corner on the bottom of the head next to the casting #.




Here's a pic of a carbed 300 head next to a 240 head to compare combustion chambers. The top head is the carbed 300 and the bottom a 1972 240.

 

Downloaded those images fordman, good info.

 

This comes up a lot and this is succinct and informative, so I'm going to sticky this.
Thanks for the pics and info Fordman

 

Great idea, sure others will find the pictures & information helpful.
