A pair of 4V big Inlet and Outlet Ports and Valved type cylinder heads that came off my 351ci Cleveland 4V V8 engine 5.8Ltr. Complete with double valve springs. In the photo you only get the Rocker arms (The pushrods and Camshaft go with the 2V Engine Block that’s also up for sale). I had the Heads overhauled about 20 years ago and they were fitted back on my 4V block for a very short period of time (about 500 – 800 miles) until I went Supercharged. I do not need 4V heads on a Supercharged engine, just standard 2 V heads will do, due to the forced air/ fuel induction, so hence the reason for sale. However, I do need the 4V engine block that has the 4 bolt main bearing carriers for increased load on the main crankshaft bearings due to extra power being produced. This is what was carried out on the heads. They had new valve guide stems (but not the harden type that you can run unleaded petrol on). New valve stem oil seals (but these might want replacing now, because they could have perished). Valves were reground and seated, and double valve springs have been fitted, ready if you want to run roller rockers. The Heads were skimmed 500 – 800miles ago when the rebuild took place, but may want checking or reskimming prior to refitting. These big valve heads are well sorted after especially for natural aspirated engines for an increase in performance and horsepower. Let me know and I will combine both items together. There’s enough here for an Engine and transmission power plant for your Hot rod.
