how much milling? hi guys, i am in process to port&polish my stock 241 heads locally cause i dont have a budget to buy new heads.. it will cost me only around 600 dollars to port and polish locally 
my question is how much milling do i need to make the compression ratio around 10.5:1 with cometic 0.40 gaskets? btw my camshaft is a 220/220 115 lsa cause my car is daily driver and i use 91 octane so i dont want more than 10.5:1 compression ratio.
thanks
