Many low level aftermarket cams (most stg 1s and some stg 2s) will be fine with stock springs and retainers ... as long as you maintain the stock redline. Personally I would opt for springs at the very least when purchasing an aftermarket cam, just for piece of mind.
Do it once ... do it right.
Id go with a bisimoto cam for a sohc... but your power goals should be ok with a stock cam... stay away from a regrind as they are pure junk... there allmost allways inaccurate and are never ground on center... id keep a stock cam before id ever get a regrind.... I would keep your stock cam and jus get a cam gear like was said before...
as far as valves,springs,retainers go.... most every aftermarket cam ive seen recomends a stiffer spring, except a stage one if your staying in your stock revlimit... (type r stuff works well for this on a b series) and if you do springs, esp. for a stg2 or more, id highly recomend valves... i have seen too many people skimp on buying valves and do stiffer springs, ad high rpms, with the stiffer spring slams the valve shut at high rpms, it will stretch and or tweak the valve and fatigue it, then the head of the valve breaks off as they are not made out of a stong enough material to handle this... and i dnt really need to say what happens from there... (there is a je piston hangin on the wall in a friends shop that backs this up... a stock valve ruiend a 500dollar set of JE pistons) and id highly recomend retainers if you have the other 2 things done... stock retainers do not like high rpms at all,,, i have seen the valve keepers pull thru stock retainers after about 9000 on a b series or under certian ammounts of boost.
but all of my experience with this is on a b series not a sohc... i cant see it being too different its all basicly the same when it comes down to it...
