my buddy was tuning in my timing about three years ago, he said he got it tuned in pretty good. So he took it for a spin and when he got back, it sounded like the engine was spitting. I opened the hood and it sounded like it was comming from under the header. I put my hand under and sure enough, there was a good amount off pressured air comming out of somewhere. I though it was just the gasket for the header. I replaced that, but its still happening. Im thinking its somthing serious, but have no idea what it could be. Could it have blown a chunk out of the head? It has been sitting for about 3 years now but want to get starting on it somtime soon. Thanks guys.
