ok, i was wondering if anyone here would know what the compression would be with a EJ257 and 98 DOHC heads. I am needing to know this, so i can decide whether i need to get new pistons or not. I am going to try and get as close as i can to 9:1 CR when i finally put that shortblock in my car. Well, i hope someone knows.. or knows how to calculate it. thanks for the help!
