Measuring PTV Clearance Question
I'm going to use the "lightweight spring and dial-indicator" method for measuring PTV clearance. I have a brand new set of .040 Cometic head gaskets.
When doing the measuring, do I install the gasket(s) and torque down the heads?
Will doing this ruin the gaskets or can I use them since the engine hasn't been run yet?
OR
Can I install the head without the gasket and use the .040 in calculating my PTV clearance values?
Thanks...
