fastrthnu Posted January 8, 2008 Report Share Posted January 8, 2008 Please clarify the question. Do you mean 66mm bore diameter? that is over stock. Head domes arent that big. Im pretty sure not even close. Pro design cool head domes will fit over a 66mm bore. I think I might have answeered? Quote Link to comment Share on other sites More sharing options...

riverbanshee Posted January 8, 2008 Author Report Share Posted January 8, 2008 I guess what I need to know is how to tell if they are for pistons over 66mm. Mine has only been bored once. This is My first cool head. Right now I have a shaved stock one on there. Quote Link to comment Share on other sites More sharing options...

Bansh-eman Posted January 8, 2008 Report Share Posted January 8, 2008 well theres two types of bore small bore and big. the big bore will work on a small bore motor you will just lose compression. if you have some calipers messure then inside diameter and post how big it is, this will determine if its BB or SB Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted January 8, 2008 Report Share Posted January 8, 2008 Regular domes have a groove for the oring. Big Bore domes dont have the outside lip that makes the groove on the regular domes. BB just have the oring go around a lip, there is no groove. Quote Link to comment Share on other sites More sharing options...
