Question 243 Heads
Anyone know the cc size on a set of 243 that have been milled .030. I know that they are around 64cc stock; and it is somewhere around .005-7 for every cc. Just wondering if anyone has actually measured them after milling...
any input?

would be approx 60.17 cc if you removed .030 as the stock cc is 64.45

Most machine shops will verify the Combustion Chamber Size after milling. Does not take much. Just some colored alcohol and the tool that pours the the fluid into a sealed CC an the head needs to be level.
