Re: No Compression

Got the head off my 1940 Super. Been over ten years since I have had it off before. The reason I have pulled the head is no compression on a few cylinders. Stuck valves open. Let it sit several months with modern gasoline. I believe the cause for stuck valves is me letting the over flow pipe from the intake manifold clog up, and gasoline pooling in the intake ports and valve stems. It hardened to a very hard glossy substance, see the two photos. Never happened to me before, is this the way of modern gasoline? Thanks
