Checking deck height

coloradohill said

I had time to measure



I had some time to check at the center of the piston at the edge of the quench pad.

Would you say it is safe to call it .020 out of the hole and order Cometic gaskets to give a .040 quench? Which would be .060 gaskets?
Thanks

Make it easy on me. Is the drivers side out of the hole .015 and .022 on the passenger side, as measured on the quench pad?

If so, you can run an .060 gasket and be ok. I’m not a fan of running with one bank .007 further out of the hole than the other. Not just the quench pad is out that far, the entire piston is.

That changes the compression ratio. By how much I’d have to do the math, but it’s enough I wouldn’t do it.

You are measuring it correctly. All it takes is a deck bridge with a dial indicator and a ratchet to turn the crank. Zero the dial indicator on the deck, position it over the QUENCH PAD of the piston and rock the piston around TDC and watch the indicator.

That kind of stuff drives me wild. It’s relatively easy to get the decks square and equal.
