Increased Airflow: The porting process involves reshaping and smoothing the intake and exhaust ports in the cylinder heads. This allows for improved airflow into and out of the combustion chamber, resulting in better combustion efficiency and increased power output.\u003c\/p\u003e\n\u003cp\u003e2. Enhanced Combustion: The improved airflow provided by the ported heads leads to better fuel atomization and more efficient combustion. This can result in increased torque and horsepower, as well as improved throttle response.\u003c\/p\u003e\n\u003cp\u003e3. Higher RPM Potential: With better airflow and improved combustion, the engine can rev higher and sustain higher RPMs without sacrificing performance. This can be especially beneficial for racing or high-performance applications where top-end power is crucial.\u003c\/p\u003e\n\u003cp\u003e4. Improved Heat Dissipation: Porting the heads can also help in dissipating heat more effectively. This can minimize the risk of overheating and improve engine reliability under demanding conditions.\u003c\/p\u003e\n\u003cp\u003eOverall, the M178 Ported Heads offer a significant performance upgrade by optimizing airflow and combustion efficiency, resulting in increased power, torque, and overall engine performance.\u003c\/p\u003e\u003ch3\u003eRelated Products\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/mercedes-amg-gt-c190-lowering-springs\"\u003eMercedes-AMG GT C190 Lowering Springs — $649.00\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/carbon-air-intake-system-o102mm-mercedes-benz-amg-gt\"\u003eCarbon Air Intake System Ø102mm Mercedes Benz AMG GT — $2490.00\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/stage-4-turbo-upgrade-m178\"\u003eMercedes-Benz AMG GT\/GTC\/GTS\/GTR\/GTRPro Stage 4 Turbo Upg... — $9999.99\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/mercedes-amg-gt-s-c-valved-exhaust-with-mid-pipes-incl-cat-delete-oem-cat-adapters-ces3-set1-2\"\u003eMercedes AMG GT\/S\/C\/R – Valved Exhaust with Mid-Pipes (in... — $5599.99\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"BreadcrumbList\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Shop\",\"item\":\"https:\/\/ypgmotorsport.com\/collections\/all\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"M178 Ported Heads\",\"item\":\"https:\/\/ypgmotorsport.com\/products\/m178-ported-heads\"}]}\u003c\/script\u003e\n\u003cdiv class=\"product-faq\" style=\"margin-top:24px;border-top:1px solid #e0e0e0;padding-top:20px;\"\u003e\n\u003ch3 style=\"font-size:18px;font-weight:bold;margin-bottom:16px;\"\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdetails style=\"margin-bottom:12px;\"\u003e\u003csummary style=\"font-weight:600;cursor:pointer;padding:8px 0;\"\u003eHow much does the M178 Ported Heads cost?\u003c\/summary\u003e\u003cp style=\"padding:8px 0 8px 16px;color:#555;\"\u003eThe M178 Ported Heads is $6500.00 through YPG Motorsport with free worldwide shipping.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"margin-bottom:12px;\"\u003e\u003csummary style=\"font-weight:600;cursor:pointer;padding:8px 0;\"\u003eDo you ship worldwide?\u003c\/summary\u003e\u003cp style=\"padding:8px 0 8px 16px;color:#555;\"\u003eYes.
