Deck Height: Is the
distance from the top surface of the block or deck to the top of the piston,
if the piston protrudes above the deck, the deck height
will be negative (if the piston top is below the deck the value is positive)add
to this value the thickness of your headgasket (always a positive value,
as should be the resultant of these to numbers).
* If you have pistons with a raised dome, you will need to measure the cc's of the dome and subtract it from your combustion chamber CC's value. If you have pistons with a recess such as valve reliefs, or dished pistons, you will need to measure the cc's of the recesses and add them to your combustion chamber CC's value. |
