Sure but how can you make 11/1 with 63cc heads?
That's gonna take custom pistons, not flat-tops, and then you get into unusual chamber shapes
I see you read the beginning and end of my post, but it looks like you missed the meat and potatoes.
To get to 11/1 with a teener@ 3.94 bore would require a TOTAL chamber volume of 66.2cc,TOTAL. After setting the piston to head distance and setting the Valve to piston clearance, and the Q. That's a lotta machining. And the decks would want to be milled and the Line hone, and those expensive Eddies shaved,and a rebalance, and crap you couldda almost built two 360s by the time all is said Ndone.
