Piston Stop Advice

Do's not matter depth of stop

Ok, I was just curious since all of them I've seen have adjustable stops. It makes sense to me that your just trying to get a equal distance.

First of all what engine is this for?

Biggest single thing (and something some commercial ones are not good) is that the stop much be rigid and not move

For a LA 360 with magnum heads. They look very simple to make I like that yours threads in and has a smooth stem instead of the threaded end touching the piston.
