Another DCR/quench/cam overlap triangle question

No disrespect intended here, as I know you know what you’re talking about. So am I wrong to shoot for the ~.040 “quench”, or just say screw it and get as thick a head gasket as I can find to lower my compression? I don’t know of any readily available Chrysler small block heads (stock casting) that were closed chamber. My heads are Cc’d at 70 cc, as I stated in my previous post. Just trying to set this up as optimal as possible with what I have. If you could answer the above question regarding head gasket and give some thought on where my cam should be installed, for instance, straight up, advanced, or retarded, I would be grateful. Thank you.
I'll try to explain as best as I can. Your chamber is recessed into the head, probably by .100 or so. That means if you piston was at zero deck, with a .040 gasket, your "quench distance" would be .140 which is not "quench" Also I'm curious about your flat top pistons you say have no valve reliefs. I believe your actual compression ratio is lower than you think
