New Compression Test after OEM HG Install

New Compression Test after OEM HG Install
So my old compression numbers with the Inline 3mm Headgasket were:
200, 200, 200, 200
After I installed the stock headgasket, drove her for an hour the results were:
257, 255, 264, 257
That seems kinda nuts don't you think? With my same gauge, my old motor was around 235-245 on a stock gasket. This thread wasn't meant to be an issue but kind of a shock. What results are you guys seeing on your motors? By the way, she only has 5,500 miles on her

I just got 275psi in each on this 20k F22.
My last 2 motors with similar miles showed 240-250psi in each. Same gauge, same method, same time of year. I want to get a baseline dyno now.

my f22 with over 60k miles of boost was recently put back to stock compression. It made about 185ish Psi across the board and now makes 220ish with a few psi variance between the cylinders. It burns a bit of oil under boost but still idles well and doesn't shoot smoke out the breather. Gotta say its impressive what a good tune and well built motor can do!
