How would you get them the same height then?
How common is this problem of dropping precups? You might be focusing on an issue that doesn't really exist.
it doesn't exist imo. the only way it can happen is if you are burning serious amount of oil or if you have a really bad injector. and even then a threaded or peened cup won't help you.

Getting them to the same height would be a matter starting the threads in the exact same spot on each hole. You can have the pre cups stop in the same spot by stopping the threads in the same place. The precups threads would also have to start in the exact same place. It's called ENGINEERING (in jun ear ring)
injun is a slang/racial term and by the fprum rules is not allowed, and for the record I have never seen one wearing an earing.

well I gues you never saw me just outta the Army, I had an earing just like a sailor.

You jarheads are so slow on the uptake sometimes.

Let's steer this thread back on course.
but seriously you can engineer the head and precups to match up, but the important part by far is the machinist and his tools. Easily do able as this type of job is commonly done in the aircraft industry.
Aircraft huh, I may know somebody for that.
so is the iron head idea going anywhere?
yea, we need boost-limitless heads..
