Due to I need to replace my old valves, so please tell me, what Overall Valve Length should I buy? Because it's not stock camshaft at all, and I'm not sure about stock (4.911 in.) valve length.
Hello Again. Glad to see you again. Regarding the valves, you'll need to remove them and inspect the condition of both the valves and the valve seats. If you're lucky they'll just need a re-grind. Then re-assemble with new seals.
