small problem with the holley 350 on my slant 6

Ok may I jump in here again. I have the same issue. Go back and see some of my old threads from last fall. Guess what I finally took the head in and this is what the shop told me. He asked if the car had been sitting and I said I just bought it and the guy told me it had not been driven much. This shop has been in business over 40 years and he is well known. He said he has never seen valves so gummed up in his life. They had to soak them to clean them. He said to get rid of the gas that is in my tank and clean everything. I am in the process of doing that right now. I could put new push rods in and get about 100 miles and it would bend #2 and #5 intake plus #3 bent once also. Crazy man
