O-235 Lycoming Mods

Anyone upgraded a O-235-C 6.5 CR 100HP Lycoming using L2C 115HP 9.5 Pistons/Cyl?

If so is it bolt on or is there machining involved?

Any better alternatives? I've heard someone sells high-comp pistons
in the 10.5 CR range.

Thanks!

LyCon, in Visalia, (sp?) CA, sells custom pistons at whatever
compression ratio you want.

I am interested in LyCon's pistons for my Conti E225. My stock pistons is 7:1
and LyCon told me that they can make a set for me with 8.6 to 1 as in IO-470N,
or higher CR if I want.

Does anyone have used LyCon's high CR pistons? Do you need to increase fuel
flow or chang inition timing with higher CR pistons?
