what the hell are you talking about?
so youve got a stock stroke crank and a stock stroke cub cylinder and you want to go to a 4mm 115rod crank, use blaster pistons and run or cut 22cc domes. adding the 4mm crank pushes the piston up 2mm more then stock, then add another 5mm for the 115 rod, so your piston is going up 7mm higher then before, add in the blaster piston that has a 6mm higher pin height, so know your piston is only 1mm higher then with your stock setup... sounds like you could just cut the dome a lil deeper and eveything will line up and be good to go right?...... sure but all your port timings are going to be way off.
bottom line is you need to get a new cylinder and crank, then use your blaster pistons and 22cc domes.
