Alright I had my head planed before I threw it on my new b16 stock short block, the machine shop said they took .005 off the head to make it completely flat.

How much will this bump my compression upto on a stock usdm b16?

 

also: for those who say "do this in tech forum". I did....no one replied....and I would like to know my compression before I put my turbo setup on.

 

Is this a B16 with 10.4:1 compression ratio stock? Also, that's 0.005" correct? If so I just did some quick math and came up with around 10.547:1 compression after milling. I could be wrong though because post-it notes and Microsoft calculator are a pain in the ***.

 

5 thousandths is more than usual. your block must have been warped?

 

probly not....the shop that did it sucked...I gave it to a guy trying to start his own shop and do it for free to help me out since I was broke...and he just took it to this dumb *** shop in town.
