Called Summit today, they may or not machine the deck surface. The person I talk to did not know who did the machine work on the blocks. I am unable to get feed back on the number of blocks that need the deck surfaces machined.
I an hoping that Ls1tech can help.

This makes 2 different sponsors selling the same block saying they use torque plates so yeah I guess I'm saying your machines shop may have lied to you over a block. I don't know the exact circumstances but you probably should have called Summit when they fond a problem with the block, you may have gotten a different block or your money back.
Im not going to sit here and argue with all you guys based off someone SAYING they use a trq plate. I know for a FACT the block i got was not machined with a trq plate. End of story. Im not bitching I will just never buy another block again. Its as simple as that.
Why not give them the chance to make it right?

Does anybody know what the deck height of there blocks are, before and after machining? Does the machine shop not measure them and just does a standard cut? The GM tolerance is +/- .005 of the 9.240 deck height. I am looking for some real world numbers. Are these blocks so good that the decks don't need machining?
The bores have been covered in this thread.
I am afraid to ask about the squareness of the deck surfaces to the crank center line.
