are the fel pro head gaskets for an 400 block-4.155 bore and aluminum heads??????

36 sedan- i havent gotten around to using your procedures quite yet as ive been very busy with work lately but i will let you knos as soon as i do.


Jerry- they are 4.160 bore head gaskets that can be used on aluminum heads.


Later today i am going to get bon ami powder and then loosen the valves up and see if it works. If not then im going to try squirting oil in the cylinders and see where the pressure is. I will also clean the plugs and then try running it without the pcv and check to see if its still burning oil. Thank you all for your input.
