I only posted it to show the cracking between the seats toward the end. I've recently seen a set of 1982 596 heads that had a similar crack. It wasn't passing obviously passing water but once the engine got up to temperature that cylinder lost about 25 PSI.
I knew why you posted it, because that video wasn't about porting at all. But he trips over himself every time he acknowledges anything I post (or anyone posts about me). Kind of funny....
