I'm almost positive you could use a ceramic high RPM ball bearing pack to support two stainless precision ground tube valves with a .0002" slip tolerance.

I want to get a small engine to test this out.

Electronic Ignition won't make more power, but it does increase reliability & reduce maintenance. Not sure I'd call it a "bang for your buck"

nother bang for bucks is water inj, just some water into your inlet keeps the carbon deposits away for better overall performance

interesting DD you found 1340cc to be the limit good stuff but to achieve 1338cc
most early A12 engines are too old to use 78mm bores but have heard of 77mm yet
sleeving is more affordable vs fitting A14 crank, rods, pistons bore honing etc.
