#302 head cc's ?

[66dartgt]

Anyone know what the stock combustion chamber cc's are for the so called #302 casting heart chamber heads ?

The set I have measure 64cc like the books say.

For reference, I CC'd a pair of 1972 318 heads with standard 1.77" 1.5" valves. They have never been machined and they came up at 67cc.

I also did a pair of 915 J heads from a 340 with ferrea 5000 valves 2.02"/1.6" and they came in at 66.5cc, however they had been machined down somewhat before I bought them, They run fine on my 318.

I think it's an interesting comparison being that there's not a dramatic difference in chamber size between all three castings.
