The Indy heads require the external oiling lines that require you to use both of the oil holes at the rear of the block. The plugs have always been hard for me to remove, but for some reason, this time it's especially tough to get out. I don't want to strip it out trying too hard with an Allen wrench.
How have you guys done it?
Thanks in advance for any help.
