don't know all the brands but the most popular are the comp cams chromoly pushrods. I think I got mine with 918 springs and locks for 130 dollars total? Anyways the installation isn't hard but will take time. You pretty much take off your coil packs, valve covers, rocker arms, and they slide right out. I took off all of the lines and hoses when I did mine to make it easier, the vacuum lines, fuel lines at the fuel rail, etc. for the fuel line make sure you buy the tool otherwise you'll break the inards and it won't seal when you put it back on. It's a cheap tool you can get at any parts store. when you pull out the pushrods roll them to see if any are bent, if it is you have possibility of more damage on that valve and check for any wear on the slots where the rods go. When you install the new ones the rocker arms are just torqued down (not sure the torque off hand) and make sure the rods are seated in the cup on the rocker. make sure the valve cover seal is clean and torque the cover down, then install everything else.
what did the car redline at and for how long? You might not have a bent pushrod but it still wouldn't be a bad thing to check or change out especially if you put a lot of abuse on the engine. If you don't see much abuse or high RPM's you can always find a set of used rods on these forums. I have my set that were in good shape if you want them.
I feel like I'm missin something so someone help me out here
