Do you honestly think that their nerves automatically are eased when you say, "Don't worry about it...I'll assume risk." ? Trust me....anyone that caters to customers doesn't want that anymore than the next guy.
Flat tappet cams are antiquated. And I still don't see any reason whatsoever to use something that comes with such a high rate of failure.
Also, to base such a strong opinion (to the point of name calling) on just a clicking sound is rather childish. Actually name calling is quite childish too.
Your engine with a hydraulic roller would make more power, have less maintenance, and would carry no risk on an initial break in.
If you ever build another engine, I honestly hope you have good luck with it. I hate to see anyone have to do an entire rebuild because they skimped on $200-300 up front.
You can repeat your little phase all you want. No one's listening.
