Did you know... that for a couple of short years that mgb had a large valve factory head on their low compression cars? They had 38cc heads instead of 42cc heads like every other model.
 1.6" intakes and same size exhaust  valves.
Putting one of these on an early 60s engine would put out a whopping 9.6:1 ish  compression -stock.
On the other hand, with the 16cc dished LC pistons, a 42cc head would make a 7.3:1 engine. - Sad.
My actual stock head decided to get a external crack after a 120 mile long drive at the common #2/3 cylinder location above the plug.
If the crack went in the head or valve water would mix with the oil and toast the engine.

New head, w new seats etc. Dont ask what this cost.
