I'm doing my best to prevent a catastrophe, that's a huge help - Thank you.
Would it be best to get the 1" spacers to make sure there is plenty of room?
like I said I have two sets and with the black Mopar performance valve covers the thinner set works great. I don’t really see the need for the thicker set on a standard set of heads. Now on something like a big block B1 head it may be a different story. They collect so much oil in the valve cover and are laid down so much if you don’t drill and tap the front and rear of the heads for drain lines (get plumbed into the oil pan) every time you set the valves a 1/2 quart of oil would be on the floor. I’m sure glad these spacers were available.
