ok guys i'm thinking of changing up my setup a little. i am currently running a 04 lq4, i am using a set of p&p heads 317 castings and they have not been milled and i am thinking of using this cam. Camshaft Specs: 229*-236*-111*-.630"-.630" my question is will i have any piston to valve clearance issues using this much lift, if not how much do you guys think i could mill my heads cuz i also want to bump up the compression ratio a little also. or is this setup just way to far fetched
