Don't worry Mark WILL make sure we will survive.
A donation page will come and I'm sure Mark will have a deep backup pay system in place, as a lot of us find this place home.

20.5cc is too small for todays pump gas for sure...(well you could if you took out good ignition timing for way retarded timing and make it even more of a pig off the bottom end power).
Some RD350 stock heads came with 22.0 and 23.0 CC heads.
The step of the squish tells the differences on these stock ones. like .022 on the 23cc and close to .011 on the 22cc heads.
350's have horrible squish clearances and in the old days we just milled the piss out of them even letting to squish OD get a little smaller just to get to .042-.046in. Back then in the day we had good leaded fuel.
It did increase the squish ratio to over 50% too and can be hard to make live at wide open hard throttles with the pump fuels today. I like no more than 45% max. more like modern designed 2 stroke chambers.

I like to try and alway use the later model RD wavy heads and not the R5 type shark fin heads when you can, as the shark fin heads have been known to crack when milled.
IMO, doing a RD400 .020in. headgasket conversion and re-machining the heads is the way I mostly go. Another reason is I can use a higher head bolt torque value to prevent headgasket failures that the 350's are prone to have with the .040in. thick ring gaskets.

Scott C. has a nice way of re machining the stock heads with a step in them  and oring to not use the crappy RD350 .040 ring gasket.
With this method it get the squish band down closer to the piston.
But have you still have to manage the squish ratio and compression ratio.

Nice one Mike!! I hadn't seen your sleeper before, perfect year too with the green...
