tried searching with no luck. what the stock cc size on a 241 casting head. am concidering purchasing some patriot 6.0 heads from a guy I know that are 68cc heads wanted to know how the compared to stock. Thanks

 

I think the stock ls1 is ~67cc and the stock 6.0L is 71cc. I could be wrong though.

 

Stock LS1 heads are 67cc and the 6.0 are 72cc. If he has 68cc heads, these are more than likely a set of our LS6 style heads that have a 68cc chamber CNC machined in them. Check to make sure they are for a stock bore because we do a 68cc version that is for a 4.125" bore.

 

Thanks I know it is off of a stock bore car, I asked him if they which heads and what cc the chambers were and that is what he told me. I will have to ask again
