*Piston
Volume: Enter a positive number for a domed piston. Negative
number for a piston with valve reliefs or dish, and 0 for a true
flat-top with no reliefs. Most flattop pistons have -4 to -6 cc's
for the valve reliefs. Check the manufacturers catalogs for exact
volumes.

for deck height |
*Gasket
Thickness & Deck Volume: Thickness of the compressed head
gasket. Typically around .040", check the manufacturers catalog
for exact thickness, or measure a used head gasket with calipers.
Also, in this field, add or subtract for the amount the piston sits
below or above the surface of the block at TDC. Example, if gasket
is 0.050" thick, and piston is 0.020" below deck, enter
a total of 0.070". If the piston is 0.010" above deck
surface, and head gasket is 0.040" thick, you'd enter 0.030". |
