GSC P-D Toyota 2JZ-GTE 23-8N Chrome Polished Exhaust Valve - 30mm Head (+1mm) - SET 12

If you're rebuilding the top end of your 1993-2005 Lexus GS300, especially with a 2JZ-GTE engine, you'll want to pay close attention to your valves. These GSC Power Division exhaust valves are a solid option for that kind of work. They feature a 30mm head diameter, which is 1mm larger than stock, giving you a bit more flow potential when you're aiming for improved performance.

These valves are made from chrome polished steel, a well-built material that helps them stand up to the heat and stress inside the combustion chamber. The +1mm oversize head is a common upgrade for tuners looking to maximize airflow through the cylinder head. This set includes 12 valves, which is exactly what you need for a complete engine build on your 2JZ-GTE.

When installing these, remember they are an oversize part, so ensure your valve seats are properly machined to accept the larger diameter. This is a critical step for proper sealing and performance. If you're building a high-performance 2JZ-GTE, these valves are a key component to consider.
