I’m in the process of taking the cam towers / heads off my ‘79 SC to get them rebuilt and the two Woodruff keys have me stumped. From what I’ve read the Woodruff keys need to come out for the cam seal to be taken out so I can get the chain housing off to pull the camshaft.
How on earth are those keys supposed to come out? I tried prying, tapping, channel lock pliers, those darn keys did not move one bit. Any help is greatly appreciated. Thx Bernd
