Closed chambers gone bad… that’s a wrap

Heck, if all else fails, and they are actually hitting, run a thicker head gasket. It's not like you're gonna lose quench. LOL
Bingo!!!! I asked where they sit out of the hole.

Cometic will make what you need. Pricey, yes, worth it, absolutely! If your slugs were, let’s just say…. .030 positive, above deck, have Cometic make a .070 gasket for .040 clearance.

Now redo the math with your numbers…. Call Summit or Cometic.
