I do have a "new" engine and noticed that the recess for the sparkplugs is deeper on the heads of this engine than on the one before, deeper enough to block sight of the piston. But, curiously, the [right side] heads from both engines have the same part number, 68-6049B. The first engine had domed pistons. This one maybe has flat tops??
I ended up using a bent wire to find TDC [more or less]. Anyone know of a better method? Or why 2 heads with the same part number are different? The one with the deeper recesses does have Ford script. The other one doesn't. A Chinese knock-off maybe?
