I'm very interested in this,i thought or i should say assumed they were the same??
If there not then what about all the 7a heads sitting on top of ABY and AAN blocks??!

I measured mine at 44.5cc

ABY head or 7A?? Can't remember which your using at the moment?

I am assuming they will be the same casting and cr is altered by piston and bore size but will get the 7a I have measured and post result here.

I have measured ABY, AAN and 7A all within .5cc of each other ~ all identical within manufacturing tolerances I'd say.

A big sigh of relief then!
