Hi Guys

Just got my 261 from the "Mawsheen shop"..... the 1958 GM manual calls for AC 44 spark plugs....of course I asked the friendly CTS parts person who gave me a blank look....... can anyone tell me what the current equivalent number would be.....
I was given Champion RC12YC....they do fit and at least will keep the dust out of the bore...but are they the proper plugs???....

For future reference and minimum maintenance I will run a Pertronix set up..... are there any high quality/long life plugs such as platinum that I can use and again what would be the brand..part number....I am not trying to be lazy but the design of my COE is such that maintenance/tune up would require removing the engine cover which is a 6 hour job just to remove....not to mention the assorted cuss words and beers!!!!

Thanks for your help.
