I just came from the garage, thought i would check a few things before heading off to work. I pulled the exhaust valve to measure it. Think i will just replace it with another Edelbrock valve, whatever they use. I poured some cleaner in the intake port and no leaks there. You can see on the right side of the intake brow that the valve was just touching that outer edge and some more deep into the brow. You can say i paid for an education in all of this. It will be awhile before i can get back to it.
