French My 250 was between 13.9-1 to 15-1 when I first had the 194 head on it sometime before I joined Inliners and start running the drags More with the car. BUT anyway I ran it on Lcheap 87 for the better part of 6yrs It would start with a Bump of the key But had to Load the clutch to shut it down.(But if i ran 112 it would shut down fine other wise. And Those Same Pistons are still being used. I have Photos of when I would blow the head gasket out and NO Pitting in Head Or pistons.
And I pulled 16mpgs with it like that with a 3.08 rears
