Spitfire headgasket, Round 2

Well, I certainly tried to do it "right" but something did not work out. While taking a test drive the car broke down and had to get flat-bedded home. When I got the car home I had zero compression in cyl 1 & 2 and only 100psi in 3 & 4. So the bad ones were clearly bad, and the "good" ones were low.

The new one was not cheap, but looks great. Just use the finest (sharpest) awl or tiny screw driver to pop off the cap (with the shift pattern in it) and below that is a hex key holding the knob on. Easey Peasey. The old knob was pretty tired. This is after popping off the cap, just remove that hex head bolt. You c

Why is the engine flat?

Why did the 911 use a horizontally opposed engine from 1964-on? It's an interesting design study. Other car makers to use a flat engine...
