Here is the website I am looking at http://www.rosspistons.com/items.php...&ItemTypeID=25
How do I find out what compression ratio's like if I was to go with the very first one on the list? I am going to have lloyd elliot do my heads and I believe the heads will be right at 58cc when he is done with them. Can anyone help me out?

 

The first pistons on the list are flattop with a 4CC valve relief.Ya need to know how far the piston is in the bore from the deck,the bore,,the CC's of the head gasket,the C Chamber CC's and the valve relief CC's.
Go to the calculator in the front of the board and figure it out.

Wallllllllllaaaaa.
