Hey guys, I overheated my car

and since the head is coming off Im looking to upgrade my springs, retainers and hopefully valves as well. I curently have 272 B.C cams, im just looking to see what people have used and what has worked best for ya'll. I am looking at the B.C springs and retainer combo, what can you say about those springs from previous experiences. I am geting a multi-layered metal head gasket along wit APR head studs as well.
Thanks for your replys
