Sleeving a low compression engine.

Is it true that when you sleeve an engine that you would eliminate the valve relief in a low compression engine? Then would it make sense to sleeve just one cylinder, boosting the compression ratio? Would you then need to machine that valve relief back into the block to equalize the compression ratio?

Keep in mind that I get these kinds of calls and questions posed to me and I'd like someone to be able to search on our site and find a quick answer or in the least a direction to head. The better our information is the better this sight will be. Good information, not more cubic inches is real power! More cubes is frosting on the cake.
Thanks guys!

Yes you would need to put the notch back ,if I'm picturing it right,on anything but a "bone stock" build.Exhaust valve clearance.

But for $200/cylinder, why not leave the low compression in and put $1600 towards something low compression friendly such as a blower?
