Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION

Number one, with that tiny engine the headers aren't too small unless you plan on spending a lot of time over 6,000 rpm. Number two, tough to pick a cam when you don't know what intake manifold and heads (intake and exhaust flows for certain) you are going to run. Oh, bye-the -bye, I'm just asking for the information for others, because I have no intention of designing a cam for you.
