Title: Inlet Port Guides Post by: Rod on June 13, 2006, 10:19:17 PM High All,
I have a grey head with minor port work. My question is "Should the Inlet Port Guides be matched to the port and manifold?" Currently the guide is slightly raised and not matched with the port work. Would this disrupt the flow hence effect performance?? As a side issue is it important to match the exhaust port to manifold?
