Radim Posted February 26, 2011 Report Share Posted February 26, 2011 When you start bleeding. I think once it reaches the Nissan or Head Stamp it's enough. Quote Link to comment
banzai510(hainz) Posted February 26, 2011 Report Share Posted February 26, 2011 when I seent them start cuting in to the A87 on bottom then I be wary. Or have alot of head saver shims. Quote Link to comment
datzenmike Posted February 26, 2011 Report Share Posted February 26, 2011 Cut as much as you like, but.... The compression will go way up The timing chain will become slack. This will advance the can timing if not adjusted... or if it even can be adjusted. Factory head thickness from the valve cover to the block mating surface is 4.248" , anything less is what has been shaved off. Quote Link to comment
inline4 Posted February 26, 2011 Author Report Share Posted February 26, 2011 its been shaved, its just a matter of what precautions need to be taken if I'm putting a head, condition unknown onto a block. okay, so if shaved = higher compression but what do I need to watch out for/run with it? I'm used to stock stuff. https://lh5.googleusercontent.com/_iyhkKE_FBV4/TWhjRlUKDHI/AAAAAAAAAaY/BVD_8kcOHVc/s640/IMG_20110225_181706.jpg Quote Link to comment
datzenmike Posted February 26, 2011 Report Share Posted February 26, 2011 Seen worse. It should be well within adjustment range if even needed. What head and how much? Here's one that's really shaved... See the bottom of the letters missing? Quote Link to comment

Stitebunny Posted March 25, 2011 Report Share Posted March 25, 2011 Did you get anywhere with this head? I have one that is shaved slightly more than yours but less than that A87 and am hoping it can be used again. Quote Link to comment
