you have confused me now?
Im going to go straight through the top like usual. depending on bore size the plate would beable to be left in place no prob or if the bore was going to be larger than the plate hole ... the plate may be only used for correct setup.Or you would bore through the plate.

Sorry was replying to abently, fixed now

the idea behind the torque plates is to beable to set the block up of of the deck plate rather than the bores which may be out slightly due to excessive wear or being machined "out" by someone who was out a few thou when clocking up or even the factory being "out"

having the blue print will allow us to locate the correct position for the bore in the block.
Bolting a torque plate to it that we know has been made to exact specs will allow us to clock up (setup) the block on the jig in exactly the right spot.

I precisely measured MLS gasket (CNC laser cut or watever) will be fine. It all depends on the accuracy of the measurer or plotter

.

The threaded stud holes may not be perfectly 90 degrees to deck of block and the bores may not be 90 degrees to deck either. So ANY torque plate will require some extra clearance for the bores and the head stud holes anyway. If you can accurately plot and measure a MLS gasket its as good as any CAD in this instant. It can only be as accurate as the original machining of the block will allow it to be.

Sorry i couldnt actaully supply you with any CAD drawings as thats really what your after

Yep.....we are on the same wave length now.
As for the MLS...... you are tottaly correct- in that youd asume they are accurate as one would assume they were designed from the very blueprints im trying to find. In theory they should be sweet....but you never know.

Cheers jeffro
