yep,thats my experiance anyway.copper gasket will not seal without cylinders being o ringed
Have encountered thr oposite too. The o'rings in the sleeves are to control cylinder pressure. However, we have seen cases where the gasket is not soft enough and not using good studs, has caused the o'rings to hold the gasket up off the block, which lets oil pour out everywhere.
Getting copper gaskets to not leak oil is a challenge.
Spraying them with Copper Coat several times, allowing it to get tacky dry between c oats, seams to work best.

I will be running 10.5:1 compression. Sounds like the 2 piece gasket is the popular opinion so I will go with it. Do you use silicone AND the o-ring in the center groove or just one/ Also, do you use any Yamabond 4 or Sealant with the composite (Cometic)gasket? Thanks Larry , Your expertise is greatly appreciated!
