Can you use paper head gasket and o-ringed head

Many strange things going in in my garage. Basically I want to slightly lower the compression on this Riva 784 I am trying to get online. Riva sent me flat top domes instead of domes for domed top pistons. I wanna ride this week. I could put it together and run 50/50 race gas or I wanted to try using a paper gasket with an o-ringed Riva head to bring the compression down, to maybe 1 gallon to 4 Torco 111, or even strait pump gas. Compression sits right now at 195 on a snapon guage.
Will it work, or must I buy another 5 gallons of race gas for the weekend??

No, I was not going to run the flat top domes!!! Just trying to get a little less compression on my existing 32cc domes. Still not good? I assume squish the issue w/ both gaskets/o-rings??

Well, FYI. I went to try it anyway, even though wax said no no. A stock headgasket isn't gonna line up with a 85.5mm hole anyways. It would have to be a custom gasket. Duh!

I 'll be running 195psi I guess till the domes come back. $$$ Race Gas $$$

I also decided to ditch the speedwerx feestyle pipe. Too much alignment crap, and it hits my lowered carbon hood. B-pipes forever.....

good on you for tring
it how we all learn
my concern was not so much the not lining up
its weas the fact that you had so much non metal surface exposed to the flame front
i know the metal ring is there but it can only take so much heat
