Ok. Things are settling down. A careful look at some part numbers tells the story. John Wikoff suggested this last night:
92 Cylinder heads ARE different for the L27 and the L67 than any other year.
93-95 Cylinder heads are the SAME.
94 was the FIRST YEAR of roller rockers for the L67
93 was the FIRST YEAR of roller rockers for the L27
92 Rockers are NOT THE SAME as the 93 L67 non-roller rockers.
So I'm probably in good shape with the heads I have. I just have different rockers, but I DON'T have the 92 heads.

Though Pat'* look like rollers (and must be according to your info) since the bearings look curved, they appear to have a black edge and a different light gray color inside that. Different from JDBs which are shiny metal. But the pic isn't as revealing as if the valve cover was off.

No poop. I was starting to line up some 94 heads.
Pat'* just look kinda dry to me.

Bear in mind the pedestal may very well be different too. So anyone with a 93 L67 wanting to upgrade for a mere 5hp may need the front and rear pedestals also.
I can't make out the part number cast into the pedestal on JDB'*, but you can JUST see it between the two rockers for the #3 cylinder.
Mine is 24501397. JDB, do you have another shot of that?

I can verify what Bill just stated about the 93. Mines an early 93, had the solid rockers, and I tried the roller setup on the ORIGINAL motor and it all bolted up fine, and the aluminum spanner thing can be reused too.
One thing I did notice though on 92 L67 ...they have pushrod guideplates in them, and the balance shaft has a splash shield on it.
