In a recent thread I noted that the ports on my 1.7 turned 2056 heads are 47x37.5mm. I don't know what the valve size is.
Is the valve size usually the same size as the port, or smaller? The heads are installed and I don't want to remove them unless I need to, but the engine is about to come out for conversion to EFI. The engines PO had the headwork done and I don't have all his notes. If the valves are the same size as the ports I am going to pull the heads to have proper fitted valves for my engine. Would too large a valve size lead to higher head temps? The PO said when I bought the motor that it ran warm and I have noted this myself even after rebuilding the bottom end in 2009. Its manageable but I do have to take care climbing hills on the freeway. |
