On a stock US 2.0 liter with the dished pistons...
If the head gasket is removed...no cylinder base gasket is installed. What is the new compression ratio...circa??? Do the valves have a chance of hitting the top of the piston... I have not doe this, so I dont know what it looks like yet...just want to see if someone knows already... Rich |

you definitely want to cc your heads and (re)set your deck height. i know it's ghetto, but i actually found it easier and more reliable to use a straight edge and feeler gauges (at TDC) to figure deck height than the depth gauge on the micro caliper-things that i have. definitely fab/find some spacers and torque down those cylinders when measuring.
it can be kind of time consuming, but if you have a wide variety of base shims at hand, it's not at all hard to get all cylinders the same spec (to the thou). in any case, i wouldn't want more than a couple thou out on each side for head sealing issues. i believe i used hylomar to seal the cylinder bases, seems to have worked well. |
