You dont want to believe the info your hearing, then buy em. Run em. Sounds like you made up your mind already. Theres a ton of people on the Facebook page that have ran em. With shitty results. And a couple that held together. After you grenade your motor and it costs 3x more to fix than just doing it right 1st time, you'll realize what were saying.
Wouldnt trust that gauge for starters. You got an orileys auto parts store nearby? Theyll loan you a tester for free. I've had that same gauge read +/- 50psi off . Or find someone local with a good gauge to borrow. Try starting it to make sure the rings are oiled? Then pull plugs, kick like hell. If your losing psi after kicking, you're leaking somewhere, and will not read accurately.
A micrometer with extendable measuring probe , find tdc, zero it out, go to bdc, and measure. The cheap compression testers can read false. Buy the best you can afford. Orileys has 1 for 46$ I've tested with same results as a snap on.
Start, warm up. Pull plugs. Use correct tester, kick as fast as u can for 6-7 kicks or till needle stops moving. Check twice each side.
Remove tank
Get micrometer
Find tdc or bdc.
Turn over till full stroke is achieved. (Plugs out will make easier)
Stock stroke is 54mm. Anything above that will tell you what + stroke it is.
