So they show 2 ways to install this girdle. One way is to have the caps milled .060", and put .005" preload on the caps with the girdle, the other way is to space the girdle above the caps, and have no preload on the caps, which way would you guys prefer, or trust the most for a 500-550 hp street motor. I know Im going overboard on the bottom end, but Im a little anal on these things, and just want a very reliable engine cause I really like to play, and beat on the car. Just want you guys input.

This is the way I did mine,,I milled the cap's and then milled the spotface (where the main stud's are) on all to a determined height then made hardened spacer's to fit the spot face at a thickness that gave a .005-.006 preload on the center of the cap, my machinist saw how they said to do it an agreed highly that the way I did it was far superior to their way of using a stack of hardened shim's to get the preload.

Where hid ya get hardened washers, better yet how did ya make them, a surface grinder, or a mill?? That stuff is pretty hard.
Will the non mill way be ok on a 500 hp engine.

Made the spacer's at a machine shop that I used to work at out of 4140 pre heat treat and made them a little long ,then after they were heat treated then I surface ground them to length, as far as the non-mill way, I really cannot answer that, I know I didn't like the process of installing them that way, so I went the extra step and used my own method, advantages of working in a machine shop, and liberty's I am going to miss by no longer working in one.

Also, do you have any pics of the installation when finished?
Thanks

milled, look closely and you will see the mill mark's, I think you are seeing a glare in the photo, these pic's show the supplied shim's, I thought I had pic's of the one's I made but I guess not.
