I have a set of 1989 S-10 4.3L TBI, NON-Vortec Heads that I will be redoing for my DAILY Driven Truck. I have a few questions on what to order...

First, This is my daily driver, I want to put stock valves back into these heads, BUT I want new of everything. I already have valve guide seals but, need to know if anyone knows the size of the STOCK Exhaust and Intake valves and which Brand, Stock #, would you guys reccomend me getting for it? I was thinking stainless steel?
Next would be the Valve Springs, which brand, Stock #, Kind should I get?
And Finially, the Rocker Arms, Should I get the stock 1.5 Ratio or up for the 1.6 Ratio? Which brand, kind, etc should I get? I have heard of people having valve cover clearence problems with the 1.6 Ratio Rockers, Is this true? Do you make valve cover spacers? I have the centerbolt plastic valve covers. I know i can buy rockers and valve springs for a Chevy Small block V8 and just have extra, what do you guyz think?
Thank you all for takein the time to read this and help me out!
Also, I will be ordering these parts through www.jegs.com or www.summitracing.com
I want to get as much performance out of these heads as i can without spending A Lot of dough, just resaonable money, and WITHOUT putting in bigger Valves and pleae dont tell me to drop in a V8!;)
Also, I am not putting in a cam. I am open to suggestions, again, thanks for your time
