Found a pile of C0DE-6051C metal head gaskets on my local CL.
Based on the old tech section, these come in .015-.020 thinner than today's FelPro or Mahl HGs (~40-45 thou). I've got my LeMons 250 and a second Lemons 250 that I'm working on...was thinking the extra compression bump is a step in the right direction.
I can run the math on the static CR, but was more curious if the old-school HGs are even a good idea to run. I'd assume the newer style are more likely to seal up the inevitable imperfections on my block/head and probably be more forgiving to distortion if/when we overheat. ...but maybe the metal ones might be more durable than the cardboard-y new ones?
Dunno if anyone has any experience/recommendations?
