I have an O-ringed block and I was running rubber coated copper HGs. They leaked and so the next step would be to cut receiver grooves in the heads. That's gonna cost me $150 plus a new set of copper HGs ($125).
If I were to switch to Cometic HGs, I would need to take out my o-rings and fill in the grooves. Has anyone sucessfully "filled in" their O-ring grooves in the block? If so, how so?
Which would be more robust? o-ringed block with rubber coated copper HGs and receiver grooves in the heads or Cometic gaskets with filled in o-ring grooves?
Also, are the cometics readily available or are they still in development for the SC? How much do they cost?
