I will be using an open element air cleaner and am wondering about the breather tube opening in the stock valve cover. I assume the best option is a push in valve cover breather. The hole is 7/8 in a stock chrome valve cover and I don’t want to drill it out. What is everyone using/options Also the oil dipstick tube.... my 430 didn’t have a tube. My 455 does but doesn’t look like the bolt flange would reach the head bolt on the alum se heads? Is the tube necessary? Lastly the ta shorty headers right rear most bolt can’t be accessed with a socket. Are guys using a stud and nut for this location or a shorter hex head bolt?
Thanks worked like a charm I figured the dipstick tube out as well but it sits about a half inch high
