This is the porting I am running on the motor in my 300SX build , it runs really well with a Coffman pipe , ported and polished exhaust manifold with the exit opened up and a single 44 carb with stock ignition.
The porting was professionally done but I am not sure by who , it is not marked anywhere , I included the pics to show the stair step in the transfers , the only addition I made was to knife edge the transfer port dividers.
This particular cylinder is 2mm o/s so if the liners look thin to you it's because they are , it still is about the same thickness as a stock 760 liner .
This should run really well at any size bore , I am running a stock head because with 2mm o/s and no base gasket the compression is just where I want it to be able to still run on pump gas.
