Hi guys I have a few questions about the block surface. I am trying to put in my hks 1.2mm metal head gasket. I just took my block to get machined and after they were finished decking it you can see tiny little hairline cracks around a few of the head bolt holes. You can barely catch your finger nail on them and the longest is probably less than a cm long. I am wondering if these will be a problem since I do not really want to buy a new block. Also, the guy told me that there was a low spot right near the front on the little piece extending from the rectangular shape of the block surface. Please let me know if you have tried reusing a block in similar condition or if you think I should not try it. I will be shooting for 400 rwhp so it will have to hold up for that. Appreciate any help and info for my problem. Thanks.
