1075 Kit Questions

Hey everyone, I had another question about putting on the cylinders. I should be getting them back from the machine shop tomorrow. I already have the pistons, pins, rings and a base gasket, but I don't seem to have the 4 rubber o-rings that go around the bottom cylinders. Are these essential for the motor? I assume they are but I can't find them anywhere. Does z1's full gasket set have these 4 gaskets in it? It didn't look like it did, but I could be wrong. Anyone know where I can get them?
Thanks

i wouldnt worry about them.make sure you scrub the bores really good before install.

I can't possibly imagine someone is charging $80 per hole to bore a KZ block.

When you buy the kit from us, boring runs $120.00 all four. We have probably done more 1075s than anyone else.
