We are running through my buddie's motor to make sure everything is cool with it before we drop it into his CRX. . .

We were thinking about milling the head to bump up the compression a tad bit. I was curious if anyone on the site has done this with the LS motor and how much the milled. I searched and found a variety of results. But if someone has personally done it. . not. . my friend did this or that. . .then I would like to know the specs YOU used. I was thinking of just going .05 but i would still like to know what the compression ratio is after milled if anyone knows how to calculate that. I have heard of .07 but I want to be safer then sorry when it comes to this kind of thing. I dont want to have to replace my friend's head and valves. . heh. . .

if you take .05 that will be almost a point up in compression.
remember also you gonna have to get cams gears to make up to make up for cam timing

for compression needs, not completely right, but close:
