Reply to "Identification & Advice Regarding My Pantera's Cylinder Heads"

Interesting!
• Who knows where to purchase a Torker style A331 in A3 size ports. Could not find anything on the Edelbrock homepage.
• The port window dimensions are cast/stock for A3s and were not ported
• The deck was not milled (I think): I have 64cm3 volume in the head, 8.9 cm3 for the gasket and 8.5 cm3 for the dished piston. Engine C.I.D. is 369 inch3 gives a CR 10,28
• The heads have still the original iron valve guides. They were first installed on my engine by the previous owner who made 5000 miles with it.
• Yes the engine was running very rich. There was a 850 CFM Holly installed. Spark plugs were always dark black and people driving behind my car where mentioning fuel smell. I went to a smaller carburetor which fixed the issue and significantly improved drivability in bumper to bumper traffic but did not change max engine power.
• The engine did 5000 miles. There is no wear on the tappets and cam. Components look like new.
• I did a leak check of the valves. They are all perfect, no leaks at all. Compression was equal and high on all cylinders
• On the ignition: I have a Duraspark box with an MSD distributor. Plugs and cables are new. All spark plugs look excellent (with the new carburetor). Timing is 16 degrees at idle. 36 degrees total.
