2002 Toyota Tundra
I am building my D16Z6 to make roughly 300 to 350 hp. One of the things I am installing is supertech springs and retainers. Is it worth while to install forged valves with them if I am running the stock valve size? Do you think larger valves are needed to hit the 350 mark? This will be a street car on pump gas. What do you all think???
