These are all pretty simple upgrades. For the valve covers, just find something from a reputable company (Summit, Year One, Edelbrock, etc.) that you like. MSD would be a good company for spark plug wires. AC Delco spark plugs. And I don't know much about radiators.

 

they sell some of those valve cover covers that go over your stock valve covers. Its a lot eaiser for some to go this route since removing the covers can be a dirty job to some. They are chrome as well. I second the MSD brand for the wires. You can get a pre made set for around $50. second vote for the delco plugs as well. The radiotor will be your choice and I would highly suggest stopping by a local radiator shop and getting a price from them. I dont reccomend buying an ebay radiator since 90% of them dont fit and are built like crap. I paid about $150 for a new radiator from a local place. it was a 3 row or something. Maybe one day when I have about $500 to throw away,I will buy a nice Be Cool one.

 

I would go with Summit Racing, Jeg's or GM brand for
valve covers. For spark plugs wires, I would use MSD
super conductor 8.5mm or GM brand. Spark plugs use
AC Delco regular or rapid fire. Radiator, I would use
a universal aluminum one like SummitRacing or Griffin has
for $180. It's a tight fit and some minor modding to fit it,
but it works awesome. Plus it's lighter than any stock
or 3 row copper replacement ones. Or for a more
direct fit, cough up $500 for a Griffin or Be Cool direct
fit one.
