Is this cam to much for a stock engine?

The biggest I might consider is the #60402 cam. Really, you'll get much better all-around performance if you go with a smaller cam but higher compression and ported heads (with good intake/headers to match). No matter what you do at the very least get those heads milled as much as possible without severely messing up your intake mounting geometry. I also agree with dgc333, 2.02" valves aren't as necessary as a compression boost or better low-lift flow.
