About this product
<p>STM DSM/Evo 4G63 head port block off plates are designed to completely seal off your intake and/or exhaust ports while you have the manifolds off. Buy the set or individually as needed.</p>
<p>Whether you're building your motor or swapping out parts, this will keep dust, debris and creatures out of the ports and also makes your fresh build much more photogenic compared to bunched up paper towels when it comes time to show it off! Also great for shipping engines.</p>
