too mild camshaft

since your bottom end is similar except for stroke and you have better top end, it would be cool to see how your engine would react to the cam/rocker ratio combo they used in this 318. he used a combo of 1.7/1 intake and 1.6/1 exhaust rockers to achieve .622"/.597" at the valve with 247 degrees at .050" lift. lobe sep was at 105 degrees
