I've heard that 94-97 12 valve heads flow better. Just wondering if there would be any issues putting one on a 1st gen. I'm also wondering why they flow better.
Thanks

I had a crack in my head on my nonIC 91. Guy at the machine shop said he had seen guys run cracks twice the size of mine in Case loaders and such with no issues, so I ran mine as it was. As long as oil, water, and cumbustion gasses stay where they belong......
