Boss 429 conventional head gaskets

Hello everyone..... So I'm looking for some information on switching my boss 429 to conventional head gaskets. I have an extra set of heads that I'm getting the o-ring lands welded up on and would like to make the conversion. Does anybody know what gasket to use?... I was hoping to retain the internal oil drain backs and oil supply. I read somewhere Eric Simone modified gaskets to make this happen..... Any information would be greatly appreciated thank you!...... Joe

It depends on the build which  gasket I use after we weld up the o-rings.  pm ,or call me with more info if you want

Also I am getting closer to having my REPLACEMENT -  O-RINGS avb for the org  BOSS 429 heads ,  Im also starting to do ROCKER arms

Looking forward to the new o-rings. Are they going to be like the originals with the steel washer inside?
