I forgot to add that they made shims for the Cox cylinders also, that fit under the cylinder between it and the case. Either a Cox part or a Dale Kirn item. It adjust the deck height plus lets you align the exhaust so it runs fore and aft. It all depends on what you want out of the engine.
Type at you later,

Hi Dan, I don't know where you can find the cylinder shims anymore. I used to get them from Joe Klause. Their sole
purpose was to shim the cylinder to be in blueprint specs; not to adjust the deck clearance. The blueprint spec shows
that at TDC the top of the piston must be dead even with the head gasket shelf. The deck clearance is set by adding
the squish band height to the head gasket dimension. Most folks do not know the Cox's mfgr tolerances were all over
the place when it came to the squish band depth of each 1702 glowhead. Dale said "They" found the squish band height
varied from .003" to .021"!
I learned a bit when listening to Dale Kirn, who helped me set up a (Blueprint) stock TD .049 to hit over 100mph with a two-line
model on 30% fuel. I also paid close attention to him about setting up propellers for 1/2A speed and 1/2A proto.
Well that's enough of this...
