Honing a C5R

My new C5R block is at the machine shop now to be finish honed. But they just told me they need to take a little bit of material out of the top of the main webbing to allow the honing machine to hone the bottom of the cylinder sleeves. Has anyone else experienced this? He showed me where it needs some mateial taken out and why, but it seems really strange that GM would put out a block (that cost over $6K) and needs the main webbing ground down a little just to be able to hone the full cylinder.

Thanks,
Derrick

If I were you I would tell your shop to stop what they are doing and find out what the deal is. HPE and MTI have a bit of experience with C5R blocks

honing a c5r block

Here at LME we mill the main webbing on all c5r blocks. If you don't it is very hard to get a straight cylinder wall.

This is a common thing on a C5R block. The fact that he is doing it shows he is acting in your best interest.
