By squish are we talking about quench height? I understand that I want between .015 and .045 or something like that. And I assumed my pistons were .025 in the hole which is pretty common for stock. I wanted a good quench height but when I saw my CR jumped up I kinda backed away. And for those wondering I used summit racing website for this. My engine shifts at 4800 never gets above 5k. Only towing I will do is a max of 2 ATVs. And I did a little research on my cam and it says it NEEDS 9.1:1 CR. cam isn't too radical but it's not stock. Max lift with the new 1.6 roller rockers will be a little over .500's.
