What kind of compression am I looking at with LS6 ported heads from Scoggin Dickey. The combustion chamber is 60cc...Will I be able to lower the compression to 9.5:1 with the proper Pistons, if so could you point me in the right direction with a link or part number to them..

OR

For the 9.5:1 Compression am I better off going with bare LS6 heads and adding the Valves and Springs and then getting a piston to lower the compression from diamond...the combustion chamber on these is 67cc

Basically I want to use the LS6 heads in some form but I also want to be around 9.5:1 Compression in a few months...What is the best way to do this..LS6 heads/Diamond pistons to lower compression...a better alternative?????

Thanks in advance,
Ralph
