"While running under it's own power",,,,,, I had to chuckle at how accurate that statement was. I've had the trans out and the clutch replaced and the rear end torn down for inspection/adjustment (more than once), the heads off TWICE and 4 different carbs since I brought the car home! Mostly I try to keep it running long enough to make it to the next "car show".
I've redone the interior and I must say, the car looks and runs great, well, when it actually IS running anyway.
I know all about the advantages of the alloy heads. I really like the original equipement look/feel the engine has now. To me, the Cobra is a time machine.
Wasn't aware of the alloy high riser heads ala 64-65. Must have been pretty rare and impossible to find an original now? NOT that Holman Moody stuff mind you, something with a part number like C4AE-etc.
