The more I think about it though, and I've said it before....you probably shouldn't sell something that has not even been tested. Blame myself more than anyone for actually BUYING something that has never been tested. I'm not even a businessman and I wouldn't dream of selling an unproven product until I had some cold, hard facts.
So him being the good guy he is, he refunded me. Don't know if this thread nudged him to do so or not. The Internet is a powerful advertising aid. Personally, I think he HAD to do the right thing.
On my end, I can't believe I did something so stupid. Yep. I got a refund on the heads. That's really cool. Did lose my time, labor, gasket, and DYNO money. Lesson learned.
