Then just to make sure it is just your heads have them sent off for a test. Hopefully you will get luck like i did and it is just a vortec head. 400.00 from napa and very simple to install. It's just torqueing in the right order. Start in the center and spiral outwards from there.
Best of luck
i think he means a couple teaspoons of oil. It would be difficult to get the teaspoons through the spark plug hole.
