so I bought a three pOrt Off A.guy.... it only had a few tanks through it had a ton of metal pinch.... I hear people say about how it takes a gallon and a half to get rid of the pinch.... I used the 20 percent fuel method to getIit Hotter Faster.. I Did Parking Lot Runs Back And Forth shutting it down and letting it cool all the way down every once in awhile and starting it back up and it took me three quarters of a gallon to get rid of the metal pinch.... what I heard that's kinda early but it has no pinch left and has tons of compression

Hey guys I got a question for ya,
I recently picked up a OS VZB Speed(old style). Has anyone here or heard of anyone rebuilding one of these with the new Arrow(5port) piston,sleeve, and rod? I am very curious to know the performance outcome in doing this.
Is it better to use the Arrow 5port sleeve or 3port sleeve?
Thanks
