My first slant build

Well i have pulled and disassembled the engine, before i go on let's discuss what i have planned, a holly 350cfm 2bbl on a cast 2 bbl intake with oversize valves, electronic ignition, a comp cams 264s with 440 lift and 264 duration camshaft.I am set on running a 10.0:1cr. please let me stress i am new to /six's so please bare with me, here's what i know so far. My chamber volume is 58/59cc across the board bore is 3.40" on all with all 6 cylinder's being round, my gasket bore is 3.50" as well as .035". deck height seem's to be .180" I am told the engine has never been rebuilt bearing's seel's and gasket's. With that in mind are these measurement's right, if how much can remove before i need to shorten pushrods and can acheive my goal without needing to do so. And yes i have read other thread's and been to slant six.org and the morei read the more confusing it seem's to get
