fyi, an 04 GTO would have 241 casting heads on it....so did someone swap 243/LS2 heads onto it?
I know it came off a LS2 GTO. The heads were removed by CMS which is a supporting vendor/tuner here in Southern California. They will be happy to vouch for the condition. But they are 243 casting heads. thanks for clarifying that!!
