The only ones that work for me is John Arruza,s sales them,, He also has a great V/C gasket. thick. lube the tube some when you slide them on. Wont damage Ring. I will ask this, Does ur spark plugs have the crush washer on them? If they do you will have oil every place. Keep it outta the Ditches!

As for orings, they seem to fit well, and as for gaskets on the plugs, yes there are gaskets. Should I not have the gaskets on the plugs? Chris from New Jersey

They fit original heads perfectly. Milodon makes (made?) the inserts as well, but I bought two sets from the guy on Ebay and have had no problems. I think I paid about $90 for them, but it was several years ago..

I unscrew them and then shove a length of fuel hose down there to grip the plug and pull it out. Same with installing the plugs, I gently guide them down on the end of the hose and spin them in by twisting the hose before torquing. Sheldon
