[QUOTE="CharlieT, post: 935370, member: 57464"] I checked that before and it came out that rounded off, a 0.010in increase should increase vol 1cc The gaskets I have are cometic and are measuring .011-12in, or around .28mm A .5mm gasket is roughly .020in thickness, I asume that must be the thicknes on a stock Honda base gasket?? If the change in vol calc is correct, then it looks like I would need .080 to get it up around 20cc. If it is .010in on squish now, adding .080in to the base would increase the squish to .090. SO if I'm looking to get a squish around .40in, then I'm looking at taking .050 off the head. Of course, this is all predicated on a .010 increase truly equaling a 1cc increase. [/QUOTE]
